Subject: [PATCH 01/12] Harden CI/CD security: pin actions, add environments,
 branch protection

- Pin third-party actions to immutable commit SHAs (softprops/action-gh-release,
  thomashampson/delete-older-releases, actions/checkout@v3) to prevent tag hijacking
- Add 'environment: release' to all publishing jobs for secrets/approval gating
- Branch protection on master already applied via GitHub API (requires PR review,
  status checks, blocks force-push and deletion)

Subject: [PATCH 02/12] Fix input validation bugs: tilde expansion, path
 traversal, whitespace args, -v shorthand

- Remove -v shorthand for --verbose (CF CLI intercepts -v before the plugin sees it)
- Expand ~ in --local-dir to the user's home directory
- Reject --local-dir values containing path traversal sequences (..)
- Validate --local-dir exists before execution, including in dry-run mode
- Reject whitespace-only --args values with a clear error message

Subject: [PATCH 04/12] Add gosec and govulncheck; bump Go to 1.24.6

- Enable gosec in golangci-lint; add targeted nolint annotations for
  intentional exec.Command("cf",...) / exec.Command(javaPath,...) usage
  and correct file permissions (0755 dirs, 0644 JAR/hash, 0600 downloads)
- Add govulncheck to PR validation and build workflows; runs in report
  mode since remaining findings are stdlib-only (require Go 1.25.x)
- Add govulncheck to scripts/lint-go.sh for local development
- Bump go.mod to 1.24.6 (fixes GO-2025-3956: exec.LookPath path confusion)

Subject: [PATCH 05/12] Fix golangci-lint v2 config; emit govulncheck findings
 as CI annotations

- Fix .golangci.yml: move G204 exclusion to linters.settings.gosec.excludes
  (v2 schema dropped issues.exclude-rules in favour of per-linter settings)
- Remove now-redundant //nolint:gosec G204 annotations across all call sites
- govulncheck: parse JSON output and emit ::warning annotations so findings
  appear inline in the GitHub Actions UI and PR diff view

 versions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Shell-quote appName in jstall sshCmd to fix G702 (command injection
  via taint analysis); add shellQuote helper using single-quote escaping
- Bump all GitHub Actions to Node.js 24-compatible versions:
  checkout v4→v6, setup-go v5→v6, setup-python v4→v6,
  setup-node v4→v6, golangci-lint-action v8→v9

Subject: [PATCH 10/12] Fix govulncheck annotation script, update deps, bump Go
 to 1.25.0

- Fix govulncheck JSON parser: output is multi-line JSON objects, not
  NDJSON; use raw_decode() instead of line-by-line json.loads()
- Upgrade golang.org/x/crypto to v0.52.0 (fixes GO-2026-5005 through
  GO-2026-5023: 13 CVEs in SSH/TLS/auth packages)
- Upgrade golang.org/x/sys to v0.45.0 (fixes GO-2026-5024)
- Bump go directive to 1.25.0 to match updated dependency requirements
