Updates flask from 3.0.3 to 3.1.3

Release notes

Sourced from flask's releases.

3.1.3

This is the Flask 3.1.3 security fix release, which fixes a security issue but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.3/ Changes: https://flask.palletsprojects.com/page/changes/#version-3-1-3

  • The session is marked as accessed for operations that only access the keys but not the values, such as in and len. GHSA-68rp-wp8r-4726

3.1.2

This is the Flask 3.1.2 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.2/ Changes: https://flask.palletsprojects.com/page/changes/#version-3-1-2 Milestone: https://github.com/pallets/flask/milestone/38?closed=1

  • stream_with_context does not fail inside async views. #5774
  • When using follow_redirects in the test client, the final state of session is correct. #5786
  • Relax type hint for passing bytes IO to send_file. #5776

3.1.1

This is the Flask 3.1.1 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.1/ Changes: https://flask.palletsprojects.com/en/stable/changes/#version-3-1-1 Milestone https://github.com/pallets/flask/milestone/36?closed=1

  • Fix signing key selection order when key rotation is enabled via SECRET_KEY_FALLBACKS. GHSA-4grg-w6v8-c28g
  • Fix type hint for cli_runner.invoke. #5645
  • flask --help loads the app and plugins first to make sure all commands are shown. #5673
  • Mark sans-io base class as being able to handle views that return AsyncIterable. This is not accurate for Flask, but makes typing easier for Quart. #5659

3.1.0

This is the Flask 3.1.0 feature release. A feature release may include new features, remove previously deprecated code, add new deprecations, or introduce potentially breaking changes. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades. Test with warnings treated as errors to be able to adapt to deprecation warnings early.

PyPI: https://pypi.org/project/Flask/3.1.0/ Changes: https://flask.palletsprojects.com/en/stable/changes/#version-3-1-0 Milestone: https://github.com/pallets/flask/milestone/33?closed=1

  • Drop support for Python 3.8. #5623
  • Update minimum dependency versions to latest feature releases. Werkzeug >= 3.1, ItsDangerous >= 2.2, Blinker >= 1.9. #5624, #5633
  • Provide a configuration option to control automatic option responses. #5496
  • Flask.open_resource/open_instance_resource and Blueprint.open_resource take an encoding parameter to use when opening in text mode. It defaults to utf-8. #5504
  • Request.max_content_length can be customized per-request instead of only through the MAX_CONTENT_LENGTH config. Added MAX_FORM_MEMORY_SIZE and MAX_FORM_PARTS config. Added documentation about resource limits to the security page. #5625
  • Add support for the Partitioned cookie attribute (CHIPS), with the SESSION_COOKIE_PARTITIONED config. #5472
  • -e path takes precedence over default .env and .flaskenv files. load_dotenv loads default files in addition to a path unless load_defaults=False is passed. #5628
  • Support key rotation with the SECRET_KEY_FALLBACKS config, a list of old secret keys that can still be used for unsigning. Extensions will need to add support. #5621
  • Fix how setting host_matching=True or subdomain_matching=False interacts with SERVER_NAME. Setting SERVER_NAME no longer restricts requests to only that domain. #5553
  • Request.trusted_hosts is checked during routing, and can be set through the TRUSTED_HOSTS config. #5636

Updates idna from 3.10 to 3.15

Changelog

Sourced from idna's changelog.

3.15 (2026-05-12)

  • Enforce DNS-length cap on individual labels early in check_label, short-circuiting contextual-rule processing for oversized input while staying compatible with UTS 46 usage.
  • Tidy core helpers: hoist bidi category sets to module-level frozensets (avoiding per-codepoint list construction), simplify length checks, and reuse the shared _unicode_dots_re from idna.core in the codec module.
  • Use raise ... from err for proper exception chaining and switch internal string formatting to f-strings.
  • Allow flit_core 4.x in the build backend.
  • Expand the ruff lint set (flake8-bugbear, flake8-simplify, pyupgrade, perflint) and apply the surfaced fixes; pin lint CI to Python 3.14.
  • Add Dependabot configuration for GitHub Actions.
  • Convert README and HISTORY from reStructuredText to Markdown.
  • Reference CVE-2026-45409 for the 3.14 advisory in place of the initial GHSA identifier.

Thanks to Felix Yan, Stan Ulbrych, and metsw24-max for contributions to this release.

3.14 (2026-05-10)

  • Removed opportunity to process long inputs into quadratic time by rejecting oversize inputs up-front. Closes a bypass of the CVE-2024-3651 mitigation. [CVE-2026-45409]

Thanks to Stan Ulbrych for reporting the issue.

3.13 (2026-04-22)

  • Correct classification error for codepoint U+A7F1

3.12 (2026-04-21)

  • Update to Unicode 17.0.0.
  • Issue a deprecation warning for the transitional argument.
  • Added lazy-loading to provide some performance improvements.
  • Removed vestiges of code related to Python 2 support, including segmentation of data structures specific to Jython.

Thanks to Rodrigo Nogueira for contributions to this release.

3.11 (2025-10-12)

  • Update to Unicode 16.0.0, including significant changes to UTS46 processing. As a result of Unicode ending support for it, transitional processing no longer has an effect and returns the same result.

Release notes

Sourced from requests's releases.

v2.33.0

2.33.0 (2026-03-25)

Announcements

  • 📣 Requests is adding inline types. If you have a typed code base that uses Requests, please take a look at #7271. Give it a try, and report any gaps or feedback you may have in the issue. 📣

Security

  • CVE-2026-25645 requests.utils.extract_zipped_paths now extracts contents to a non-deterministic location to prevent malicious file replacement. This does not affect default usage of Requests, only applications calling the utility function directly.

Improvements

  • Migrated to a PEP 517 build system using setuptools. (#7012)

Bugfixes

  • Fixed an issue where an empty netrc entry could cause malformed authentication to be applied to Requests on Python 3.11+. (#7205)

Deprecations

  • Dropped support for Python 3.9 following its end of support. (#7196)

Updates urllib3 from 2.2.3 to 2.7.0

Release notes

Sourced from urllib3's releases.

2.7.0

🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project after a sharp decline in financial support. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.

Thank you for your support.

Security

Addressed high-severity security issues. Impact was limited to specific use cases detailed in the accompanying advisories; overall user exposure was estimated to be marginal.

  • Decompression-bomb safeguards of the streaming API were bypassed:

    1. When HTTPResponse.drain_conn() was called after the response had been read and decompressed partially. (Reported by @​Cycloctane)
    2. During the second HTTPResponse.read(amt=N) or HTTPResponse.stream(amt=N) call when the response was decompressed using the official Brotli library. (Reported by @​kimkou2024)

    See GHSA-mf9v-mfxr-j63j for details.

  • HTTP pools created using ProxyManager.connection_from_url did not strip sensitive headers specified in Retry.remove_headers_on_redirect when redirecting to a different host. (GHSA-qccp-gfcp-xxvc reported by @​christos-spearbit)

Deprecations and Removals

  • Used FutureWarning instead of DeprecationWarning for better visibility of existing deprecation notices. Rescheduled the removal of deprecated features to version 3.0. (urllib3/urllib3#3763)
  • Removed support for end-of-life Python 3.9. (urllib3/urllib3#3720)
  • Removed support for end-of-life PyPy3.10. (urllib3/urllib3#4979)
  • Bumped the minimum supported pyOpenSSL version to 19.0.0. (urllib3/urllib3#3777)

Bugfixes

  • Fixed a bug where HTTPResponse.read(amt=None) was ignoring decompressed data buffered from previous partial reads. (urllib3/urllib3#3636)
  • Fixed a bug where HTTPResponse.read() could cache only part of the response after a partial read when cache_content=True. (urllib3/urllib3#4967)
  • Fixed HTTPResponse.stream() and HTTPResponse.read_chunked() to handle amt=0. (urllib3/urllib3#3793)
  • Updated _TYPE_BODY type alias to include missing Iterable[str], matching the documented and runtime behavior of chunked request bodies. (urllib3/urllib3#3798)
  • Fixed LocationParseError when paths resembling schemeless URIs were passed to HTTPConnectionPool.urlopen(). (urllib3/urllib3#3352)
  • Fixed BaseHTTPResponse.readinto() type annotation to accept memoryview in addition to bytearray, matching the io.RawIOBase.readinto contract and enabling use with io.BufferedReader without type errors. (urllib3/urllib3#3764)

3.1.3

This is the Werkzeug 3.1.3 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes vs 3.1.0.

PyPI: https://pypi.org/project/Werkzeug/3.1.3/ Changes: https://werkzeug.palletsprojects.com/en/stable/changes/#version-3-1-3 Milestone: https://github.com/pallets/werkzeug/milestone/41?closed=1

  • Initial data passed to MultiDict and similar interfaces only accepts list, tuple, or set when passing multiple values. It had been changed to accept any Collection, but this matched types that should be treated as single values, such as bytes. #2994
  • When the Host header is not set and Request.host falls back to the WSGI SERVER_NAME value, if that value is an IPv6 address it is wrapped in [] to match the Host header. #2993

3.1.2

This is the Werkzeug 3.1.2 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes vs 3.1.0.
