From 2f3925e15c28673b46c6b07b47df5b99056e8284 Mon Sep 17 00:00:00 2001 From: Jarek Potiuk Date: Sat, 24 Oct 2026 22:44:17 +0200 Subject: [PATCH] feat(security): run every security skill without project adoption A maintainer who installed Magpie for themselves passed pre-flight and then stopped mid-run: vetted-ops and generate-cve-json only read the committed .apache-magpie-overrides/. Both now fall back to the personal layer; setup config drafts them. The personal vetted-ops policy gets the same tamper protection as the committed one (new required deny rules), and vetted-ops reads it only in those protected shapes and never through a symlink. A marketplace install had no /tools at all. The new magpie-security-tools substrate plugin carries the tools the security skills run; its session hook materialises a writable copy per version at ~/.cache/apache-magpie/framework/ with `current` pointing at it, so the skills' `uv run --project /tools/` works unchanged. Setup installs it with magpie-security, and pre-flight and upgrade name it when it is missing. Wording: no longer claims to be the snapshot, user.md reads follow the documented order, and issue-fix never saves personal data into the committed overrides.

In particular, the script produces: + +* ``affected[]`` entries with ``vendor``, ``product``, a version-less + ``packageURL`` (``pkg:pypi/apache-airflow``) and a semver range. The + purl is the CNA's recommended package identifier: Vulnogram derives + the legacy ``collectionURL`` / ``packageName`` pair from it when the + record is serialised for publication, so the generator emits that + pair only for a product with no purl at all + (``product.purl_type = "none"``); +* a ``descriptions[]`` entry with both a plain ``value`` and an HTML + ``supportingMedia`` alternative (Vulnogram's WYSIWYG mode expects + both); +* ``metrics[].other`` with ``type`` = *"Textual description of severity"* + and ``content.text`` = the severity word; +* ``problemTypes[].descriptions[]`` with ``cweId``, ``description`` and + ``type`` = *"CWE"*; +* ``credits[]`` entries from the *Reporter credited as* field + (``type: "finder"`` by default; ``type: "tool"`` when the credit + matches the bot/AI policy in + ``tools/cve-tool-vulnogram/bot-credits-policy.md`` — Dependabot, Renovate, + Snyk, scanners, ``*-bot`` / ``*[bot]`` handles, etc.) and the + *Remediation developer* field (``type: "remediation developer"``) + — both newline-separated, with the ``Full Name, Affiliation`` + pattern preserved as one credit; the ``--remediation-developer`` + CLI flag still works as an additional / override mechanism on top + of the body field; +* ``references[]`` with automatic ``tags`` (``patch`` for + ``github.com/.../pull/...`` URLs, ``vendor-advisory`` for + ``lists.apache.org``/``security.apache.org``). URLs from the + tracking-issue's *Public advisory URL* body field are picked up + automatically and tagged as ``vendor-advisory``; URLs from the + *Security mailing list thread* field are **deliberately not** exported + because that field holds the internal ``security@airflow.apache.org`` + thread URL, which 404s for anyone outside the security team; +* ``providerMetadata.orgId`` and ``cveMetadata.assignerOrgId`` set to + the ASF org id; +* an ``x_generator`` annotation so the origin of the JSON is visible. + +The output is **deterministic**: the same issue body and the same CLI +flags always produce the same JSON bytes.

The `allocate` request doubles as the membership check, so you may be asked to approve twice. +The token comes back to the script directly, over a redirect to a listener on `127.0.0.1` and a code exchange protected with PKCE, so nothing is copied or pasted and the token never appears in a URL. +Pass `--scope read`, `write` or `allocate` to fetch just one of them (the default is `--scope auto`). +The token file then records the PMC and scope, and `vulnogram-api-check` shows them. + +If the browser does not open, the script prints the URL to open yourself. +Before opening the browser the script checks that the deployment has `/users/token/authorize`; +if it does not, the script falls back to the steps below. + +### Copying a token by hand + +1. **Open `https://cveprocess.apache.org/users/token` in a regular + browser.** + If you are not logged in yet, the ASF OAuth flow runs first: username, password, and MFA, all in the browser. + None of it passes through this tool. + +2. **Copy one token from the table.** + The page lists an `(unrestricted)` token, plus an `allocate` and a `write` token for each PMC you belong to. + Pick the **`write` token for your PMC**: it can read and update CVE records and nothing else. + The `(unrestricted)` token works too, but can also allocate CVEs for any PMC you belong to; use it only if you need to act across PMCs. + The `allocate` tokens are refused on the record endpoints this tool uses. + +3. **Run the setup script.** The token is read via `getpass` + so it does not echo to the terminal: + + ```bash + uv run --project /tools/cve-tool-vulnogram/oauth-api vulnogram-api-setup + ``` + + Optional flags: + + | Flag | Purpose | + |---|---| + | `--host` | Vulnogram host. Default: `cveprocess.apache.org`. | + | `--pmc` | Get the token through the browser for this PMC instead of pasting it (see *Browser approval*). | + | `--scope` | `read`, `write` (default) or `allocate` — the scope `--pmc` asks for. An `allocate` token is stored separately (see *Allocating a CVE*). | + | `--from-address` | ASF account address recorded in the token file (informational). Defaults to `$VULNOGRAM_FROM`, then `git config user.email`. | + | `--out` | Output path for the token file. Default: `~/.config/apache-magpie/vulnogram-session.json`. | + | `--skip-validate` | Skip the live HTTP probe after writing. Use only if the host is unreachable from the box running setup but the token is known good. | + + The script writes the file atomically with mode 600 and + chmods the parent directory to 700. + +4. **Smoke-test by running the probe:** + + ```bash + uv run --project /tools/cve-tool-vulnogram/oauth-api vulnogram-api-check + ``` + + Output `valid` (exit 0) means the token is live and the API + path is ready for use. + +A token file written by an older version of this tool holds a browser session cookie instead. +The tool refuses to use it and asks you to re-run setup with a token. + +## Allocating a CVE + +Where the deployment supports it (`vulnogram-api-check --server` prints `supported`), a CVE can be allocated without the `/allocatecve` form. +Get an `allocate` token once per login session, through the browser approval: + +```bash +uv run --project /tools/cve-tool-vulnogram/oauth-api vulnogram-api-setup --pmc +``` + +It is stored in `~/.config/apache-magpie/vulnogram-allocate-session.json` (or `$VULNOGRAM_ALLOCATE_SESSION`), next to the record token, which it leaves alone. +`vulnogram-api-check --allocate` checks it with an `/allocatecve` request whose empty title cannot allocate anything. +Then: + +```bash +uv run --project /tools/cve-tool-vulnogram/oauth-api vulnogram-api-allocate \ + --pmc --title '' +``` + +Nothing is asked interactively, and the first stdout line is the allocated `CVE-YYYY-NNNNN`. +Optional `--message-id` / `--list-id` record the report thread on the new record. +Exit codes: 0 allocated; 1 token expired; 2 no allocate token; 3 error; +4 the server answered HTML with no ID (check the PMC's records in the browser); +5 the PMC cannot allocate directly, so Vulnogram mailed the request to the security team; +6 the ID is reserved (and printed) but its record was not saved. + +Every successful call reserves a new ID, so the command never retries; when the outcome is unclear, check Vulnogram before running it again. +A deployment without this support has no API allocation: `--scope allocate` stops with exit 4, and allocation goes through the form +(see [`../allocation.md`](https://github.com/apache/magpie/blob/main/tools/cve-tool-vulnogram/allocation.md)). + +## How the token expires + +Tokens are short-lived by design — hours, not days — and ASF Vulnogram does not offer long-lived ones. +A token lives exactly as long as the browser login that minted it: when that server-side session times out, or you log out of `cveprocess.apache.org`, the token stops working. +Reloading `/users/token` during the same login shows the same token; a new one comes only with a new login. + +When the token has expired, the next API call returns `SessionExpired`: + +```text +✗ Vulnogram redirected to the login page — the Bearer token is expired or invalid. + Re-run `vulnogram-api-setup --pmc ` (recommended) or log in again in the browser and re-run `vulnogram-api-setup` with the new token from /users/token. +``` + +Re-running setup is a 30-second operation: with `--pmc `, approve the new token in the browser; +without it, open `/users/token`, log in again if prompted, copy the new token, paste it back. +The agentic skills detect `expired` automatically via `vulnogram-api-check` +and surface the re-setup hint in the same proposal +they would otherwise propose the API path in. + +## Confidentiality + +The token grants the record access its scope allows — for a PMC `write` token, reading and updating that PMC's CVE records — until it expires. +Treat it like any other credential: + +- The setup script writes the file with mode 600 and chmods its + parent directory to 700; do not loosen those. +- Do **not** commit the token file.

The move *clears* the record +for `cve.org`; it does not submit it. Submission to CVE Services is +performed by the Vulnogram administrators (the ASF security team) and +can take hours or longer, so a record sitting in `PUBLIC` while +`cveawg.mitre.org` still 404s is the expected waiting state rather than +a failure. The state move used to be intentionally human-only (a +Vulnogram UI button click) because of the out-of-band side effects. The post-2026 +convention drives it from `security-issue-sync` on the +*"published archive URL captured"* gate: at that point the advisory +has provably shipped on ``, which is the same real-world +signal a human would use before clicking the button. + +Mechanics: Vulnogram's state machine lives in the +``CNA_private.state`` field of the document body. This script: + +1. Fetches the current stored JSON via ``GET /
/json/``. +2. Sets ``CNA_private.state = "PUBLIC"`` (preserves every other + field — this is a state-flip only, not a content edit). +3. POSTs the modified document back via the same path + :class:`vulnogram_api.client.update_record` already uses. + +If the record is not currently in ``REVIEW`` state, the script +refuses the transition with a non-zero exit (a sync that re-runs +the publish on a tracker that already published is a bug, not an +idempotent no-op — surfacing it loudly is the right escalation). + +The companion :mod:`vulnogram_api.record_update` script writes +arbitrary JSON to a record. ``record_publish`` is intentionally +narrower: it only flips the state field, so a future schema change +to the body cannot accidentally smuggle through the publish path. +""" + +from __future__ import annotations + +import argparse +import re +import sys + +from vulnogram_api.client import ( + RecordSaveFailed, + SessionExpired, + VulnogramAPIError, + get_record, + record_body, + update_record, +) +from vulnogram_api.credentials import Session, locate_session + +CVE_ID_RE = re.compile(r"^CVE-\d{4}-\d{4,7}$") + + +class UnexpectedRecordState(VulnogramAPIError): + """Refuse to publish a record that is not currently in ``REVIEW``.""" + + +def parse_args(argv: list[str] | None = None) -> argparse.Namespace: + ap = argparse.ArgumentParser( + description=(__doc__ or "").split("\n\n", 1)[0], + ) + ap.add_argument( + "--cve-id", + required=True, + help="The CVE ID, e.g. CVE-2026-12345.", + ) + ap.add_argument( + "--credentials", + default=None, + help=( + "Path to the session JSON.

This +file defines what the skills expect from an adapter, what the +single shipping adapter (ASF Security relay) does today, and how +adopters declare which adapters are enabled in +[`/project.md`](https://github.com/apache/magpie/blob/main/plugins/magpie-setup/templates/project.md). + +The framework default is the ASF Security relay adapter, which is +the only one shipping in the tree today. The contract exists so +that adopters whose security inbox sits behind huntr.com, +HackerOne, GitHub Security Advisories, an internal SOC, or any +other forwarding service can plug in an adapter without +patching the skill bodies. + +## Prerequisites + +- **Runtime:** None — this is a prose adapter *contract*; no executable + ships in this directory. The interface is implemented by the security + skills that dispatch through it. +- **CLIs:** None. +- **Credentials / auth:** None directly; consuming skills authenticate + through the mail-source layer (e.g. Gmail) for inbound reads and drafts. +- **Network:** None directly — the contract performs no I/O. Mail + fetch/draft happens in the [`tools/mail-source`](https://github.com/apache/magpie/blob/main/tools/mail-source/contract.md) layer. + +## What "a relay message" means + +Many security reports never reach the project's security inbox +directly. The original reporter files with a third-party broker — +the ASF Security team at `security@apache.org`, huntr.com, +HackerOne, GHSA — and the broker forwards the report to the +project. On the inbound thread, the broker is the visible +correspondent; the actual reporter is one hop away, reachable +only by asking the broker to relay messages back. + +This matters for three skill behaviours: + +1. **Credit extraction.** The `From:` header of a relay message + names the broker, not the reporter. Per the bot/AI credit + policy in + [`tools/cve-tool-vulnogram/bot-credits-policy.md`](https://github.com/apache/magpie/blob/main/tools/cve-tool-vulnogram/bot-credits-policy.md) + the tracker's *Reporter credited as* field must name the + external reporter, so the skill has to pull the name from the + message body (the broker's preamble convention) instead of + from the header. +2. **Reply routing.** Drafts intended for the reporter must go + through the broker — but addressed to the broker, with the + reporter-facing content folded inside as a paste-ready block + the broker can copy verbatim into their reply to the reporter. + See [`tools/gmail/asf-relay.md`](../gmail/asf-relay.md) for + the paste-ready-block convention introduced in PR #375. +3. **Question batching.** The project should not pester the + broker with every workflow chatter event. The + [`docs/security/forwarder-routing-policy.md`](https://github.com/apache/magpie/blob/main/docs/security/forwarder-routing-policy.md) + policy doc — which consumes this contract — defines which + milestones get relayed and which stay on the project side. + +A forwarder-relay adapter is the seam that lets each skill ask +the right adapter "is this a relay message? whose credit is in +it? how do I draft back through it?" without hard-coding the +ASF preamble or the `@apache.org` sender pattern. + +## Today's adapters + +| Adapter | Status | Inbound channel | Reference doc | +|---|---|---|---| +| `asf-security` | shipping | Mail from `security@apache.org` or a personal `@apache.org` address with the ASF forwarding preamble | [`tools/gmail/asf-relay.md`](../gmail/asf-relay.md) | +| `huntr-relay` | placeholder | Mail from huntr.com's notification address with the huntr disclosure preamble | not implemented — contract slot only | +| `hackerone-relay` | placeholder | Mail from HackerOne's notification address with the HackerOne handoff preamble | not implemented — contract slot only | +| `ghsa-relay` | placeholder | Mail forwarded from a GHSA private report by the GitHub notification system | not implemented — contract slot only | +| `custom` | escape hatch | Adopter-specific broker (internal SOC, third-party VRP, mailing-list relay) | adopter ships their own adapter dir | + +Only `asf-security` is wired in. The other rows are reserved +contract slots: when an adopter needs huntr.com or HackerOne +support, they implement an adapter directory under +`tools/forwarder-relay//` that satisfies the interface +below, and add `` to the `forwarders.enabled` list in +their `/project.md`. + +The ASF-security adapter's `preamble_match` regex, +`credit_extraction_rule`, +`contact_handle` +(the `security@apache.org` default, +declared org-level in [`organizations/ASF/organization.md`](https://github.com/apache/magpie/blob/main/organizations/ASF/organization.md) +and inherited through project.md `forwarders.asf-security.contact_handle`), +and `reporter_addressing_block` convention +all live in [`tools/gmail/asf-relay.md`](../gmail/asf-relay.md). +This is the only forwarder adapter shipping today; +the contract above describes the interface for additional adapters. + +### Sub-skill consumers + +ASF adopters install the optional sub-skill +[`security-issue-import-via-forwarder`](https://github.com/apache/magpie/blob/main/plugins/magpie-security/skills/issue-import-via-forwarder/SKILL.md) +to enable forwarder-aware handling. The sub-skill consumes the +`forwarders.enabled` config knob from +[`/project.md`](https://github.com/apache/magpie/blob/main/plugins/magpie-setup/templates/project.md) +and runs after the main classification cascade in +`security-issue-import`, `security-issue-invalidate`, and +`security-issue-sync`. Generic skill bodies no longer carry +the ASF-relay row inlined in their main classification tables +— they reference the sub-skill as the *"follow this if +forwarder mode is enabled"* extension instead. + +## Interface + +A forwarder-relay adapter exposes the following operations. Skills +dispatch through this interface; they do not import adapter +internals directly. + +### `detect(message) -> adapter_name | null` + +Given a fetched mail-source message (`From`, `Subject`, +`Body`, `Date`, `Message-ID`, headers), return the adapter's +own name if the message is a relay message handled by this +adapter, or `null` if not. + +Detection is the OR of two signals: + +* **Sender pattern.** A regex or set-membership check against + the `From:` address. ASF Security: `security@apache.org` OR + any `*@apache.org` address. huntr: huntr.com's outbound + notification address. HackerOne: HackerOne's notification + address. +* **Preamble match.** A regex against the first ~400 characters + of the message body, anchored to the broker's standard + forwarding header. ASF Security: *"Dear PMC, The security + vulnerability report has been received by the Apache Security + Team …"*. + +Both signals are evaluated; either one matching is sufficient, +but the adapter MAY require both for higher-confidence cases. +The skill calls each enabled adapter's `detect()` in the order +listed under `forwarders.enabled`; first non-null wins. + +**Lifecycle:** called by `security-issue-import` Step 3 +(classification), and by `security-issue-sync` Step 2b when +re-reading an existing tracker's inbound thread for routing +decisions. + +### `extract_credit(body) -> {name, kind, raw_string} | null` + +Given the relay-message body, extract the original reporter's +credit. Returns: + +* `name` — the human-readable reporter name as it appears in + the body. Used verbatim in the tracker's *Reporter credited + as* field unless the reporter later requests a different + rendering through a credit-preference exchange. +* `kind` — one of `human` (named individual), `tool` + (automated scanner like `bugbunny.ai`, `protectai/modelscan`), + `service` (a broker / VRP / SOC operating on someone else's + behalf). Drives the bot-credit policy gate in + [`tools/cve-tool-vulnogram/bot-credits-policy.md`](https://github.com/apache/magpie/blob/main/tools/cve-tool-vulnogram/bot-credits-policy.md). +* `raw_string` — the exact substring lifted from the body + (e.g. *"This vulnerability was discovered and reported by + bugbunny.ai"*). Stored so a later sync can diff against the + current tracker field and detect that the reporter has been + manually overridden. + +Returns `null` when the body does not contain a credit line in +the adapter's expected shape. The skill then surfaces a "credit +unknown — please confirm before drafting the receipt" prompt +rather than guessing. + +**Lifecycle:** called by `security-issue-import` Step 4 (field +population for the new tracker body), and by +`security-issue-sync` Step 2b when reconciling the tracker +field against the latest read of the thread. + +### `contact_handle` (attribute) + +The GitHub-style handle +(or back-channel identifier, such as a shared-inbox address) +of the relay contact the skills should `@mention` or address when proposing a draft. +For ASF Security the org-level default is the `security@apache.org` shared inbox +(per [`organizations/ASF/organization.md`](https://github.com/apache/magpie/blob/main/organizations/ASF/organization.md)); +an adopter whose relays come through an individual liaison +overrides it with that person's handle (e.g. `@raboof`). +For huntr the handle would be huntr's program-issued contact. +Lifted into config so the skill body never hard-codes a name. + +The handle MAY be a list of fallbacks (`[@raboof, security@apache.org]`) +for adapters whose contact rotates; +the skill picks the first available one +and surfaces the chosen handle in the proposal recap. + +### `preamble_match` (attribute) + +The regex used by `detect()`. Exposed as a read-only attribute +so that: + +* `security-issue-import` can print the matched preamble in its + Step 3 classification proposal ("detected as ASF Security + relay because the body starts with ``"), + giving the human reviewer a one-line "yes this looks right" + affordance; +* the test harness in + [`tools/skill-and-tool-validator/`](https://github.com/apache/magpie/blob/main/tools/skill-and-tool-validator) + can replay sample bodies through the adapter and assert the + detect outcome. + +### `reporter_addressing_block(...) -> string` + +Render the paste-ready block convention introduced in +[`tools/gmail/asf-relay.md`](../gmail/asf-relay.md) — the +fenced block addressed to the reporter in the project's voice, +signed *" security team"*, inside a wrapper addressed +to the forwarder asking them to forward it verbatim. The +adapter owns the exact wrapper wording; the inner reporter +block is built by the calling skill and passed in. + +Parameters: + +* `forwarder_first_name` — for the *"Hi "* salutation + on the wrapper. +* `reporter_first_name` — for the *"Hello "* salutation + on the inner block, when known. +* `links` — list of `(label, url)` pairs (GHSA URL, CVE + record URL, advisory URL) the wrapper prints near the top + so the forwarder can one-click context-switch on their side. +* `inner_body` — the project's reporter-facing text. The + adapter wraps it in the paste-ready block; it does not + modify the inner content. + +The adapter's responsibility is the wrapper shape: where the +links go, how the inner block is fenced, how the signature +attaches. The reason this is in the adapter rather than in +the skill is that different brokers have different forwarding +conventions — huntr.com expects the inner block to be a +markdown comment that pastes back into their UI; ASF Security +expects a `---`-fenced plaintext block. One skill body, many +adapter renderings. + +**Lifecycle:** called by `security-issue-import` Step 7 +(receipt-of-confirmation draft), by `security-cve-allocate` +Step 4 (CVE-allocation notification draft), by +`security-issue-sync` Step 2b (status-update drafts), and by +`security-issue-invalidate` Step 5d (invalidation notice draft). + +### `via_forwarder_question_mode` (attribute) + +A boolean signalling how the adapter prefers credit-preference +questions to be handled: + +* `true` — fold the credit-preference question into the + **same** receipt-of-confirmation draft, addressed to the + reporter via the paste-ready block. The forwarder makes one + forward-and-paste action total. This is the right default + for adapters where the broker prefers not to be a question + router (ASF Security: yes). +* `false` — send the credit-preference question on a + **separate** draft, framed as a back-channel request to the + forwarder (*"please ask the reporter their credit + preference"*). This is appropriate for adapters where the + broker actively reviews each exchange (some HackerOne + programs). + +The skill body branches on this attribute in +`security-issue-import` Step 7 and `security-cve-allocate` +Step 4 instead of carrying an `if asf_relay:` check inline. + +## Skills that consume this contract + +| Skill | Step | What the skill calls | +|---|---|---| +| [`security-issue-import`](https://github.com/apache/magpie/blob/main/plugins/magpie-security/skills/issue-import/SKILL.md) | Step 3 — classification | `detect()` on every enabled adapter; the first non-null return classifies the candidate as a relay import | +| `security-issue-import` | Step 4 — field population | `extract_credit()` for the *Reporter credited as* field | +| `security-issue-import` | Step 7 — receipt-of-confirmation draft | `reporter_addressing_block()` + `via_forwarder_question_mode` to fold the credit-preference question | +| [`security-issue-sync`](https://github.com/apache/magpie/blob/main/plugins/magpie-security/skills/issue-sync/SKILL.md) | Step 2b — draft routing | `contact_handle` + `reporter_addressing_block()` for any reporter-facing draft (CVE-allocated, fix-merged, advisory-shipped) on a relay tracker | +| [`security-issue-invalidate`](https://github.com/apache/magpie/blob/main/plugins/magpie-security/skills/issue-invalidate/SKILL.md) | Step 5d — ASF-relay branch | `reporter_addressing_block()` for the polite-but-firm invalidation notice routed through the forwarder | +| [`security-cve-allocate`](https://github.com/apache/magpie/blob/main/plugins/magpie-security/skills/cve-allocate/SKILL.md) | Step 4 — dual-mode draft | `via_forwarder_question_mode` to decide whether the CVE-allocation draft folds in the credit-preference ask or sends it separately | +| [`tools/gmail/asf-relay.md`](../gmail/asf-relay.md) | reference doc for the shipping adapter | this whole file is the formal contract that `asf-relay.md` documents prose-style | + +## ASF default — ASF Security forwarder + +The ASF Security adapter is the one shipping today.

It is the one implementation of the +body-field contract (tools/body-field-contract/contract.md): every reader and +writer of a field, generate-cve-json included, goes through it. + +The contract: + +- lines end at ``\\n``, ``\\r\\n`` or ``\\r`` (CommonMark's line endings, + not every character ``str.splitlines`` breaks on); +- **every line that starts, at column 0, with ``###`` followed by a space, + a tab or the end of the line ends the current field and starts the next + one, code block or not.** No fence, Jira macro or duplicate heading left + in one field's text can therefore make it absorb the next field (a + private mailing-list URL, say): a value is always exactly one section of + that split.
