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 gunicorn from 19.5.0 to 22.0.0

Release notes

Sourced from gunicorn's releases.

Gunicorn 22.0 has been released

Gunicorn 22.0.0 has been released. This version fix the numerous security vulnerabilities. You're invited to upgrade asap your own installation.

Changes:

22.0.0 - 2024-04-17
===================

use utime to notify workers liveness
migrate setup to pyproject.toml
fix numerous security vulnerabilities in HTTP parser (closing some request smuggling vectors)
parsing additional requests is no longer attempted past unsupported request framing
on HTTP versions < 1.1 support for chunked transfer is refused (only used in exploits)
requests conflicting configured or passed SCRIPT_NAME now produce a verbose error
Trailer fields are no longer inspected for headers indicating secure scheme
support Python 3.12

** Breaking changes **

minimum version is Python 3.7
the limitations on valid characters in the HTTP method have been bounded to Internet Standards
requests specifying unsupported transfer coding (order) are refused by default (rare)
HTTP methods are no longer casefolded by default (IANA method registry contains none affected)
HTTP methods containing the number sign (#) are no longer accepted by default (rare)
HTTP versions < 1.0 or >= 2.0 are no longer accepted by default (rare, only HTTP/1.1 is supported)
HTTP versions consisting of multiple digits or containing a prefix/suffix are no longer accepted
HTTP header field names Gunicorn cannot safely map to variables are silently dropped, as in other software
HTTP headers with empty field name are refused by default (no legitimate use cases, used in exploits)
requests with both Transfer-Encoding and Content-Length are refused by default (such a message might indicate an attempt to perform request smuggling)
empty transfer codings are no longer permitted (reportedly seen with really old & broken proxies)

** SECURITY **

fix CVE-2024-1135

1. Documentation is available there: https://docs.gunicorn.org/en/stable/news.html
2. Packages: https://pypi.org/project/gunicorn/

Gunicorn 21.2.0 has been released

Gunicorn 21.2.0 has been released. This version fix the issue introduced in the threaded worker.

Changes:

21.2.0 - 2023-07-19
===================
fix thread worker: revert change considering connection as idle .

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)

Documentation

• Various typo fixes and doc improvements.

Bugfixes

• The SSLContext caching feature originally introduced in 2.32.0 has created a new class of issues in Requests that have had negative impact across a number of use cases. The Requests team has decided to revert this feature as long term maintenance of it is proving to be unsustainable in its current iteration.

Deprecations

• Added support for Python 3.14.
• Dropped support for Python 3.8 following its end of support.

Updates werkzeug from 0.15.5 to 3.1.6

Release notes

Sourced from werkzeug's releases.

3.1.6

This is the Werkzeug 3.1.6 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/Werkzeug/3.1.6/ Changes: https://werkzeug.palletsprojects.com/page/changes/#version-3-1-6

• safe_join on Windows does not allow special devices names in multi-segment paths. GHSA-29vq-49wr-vm6x

3.1.5

This is the Werkzeug 3.1.5 security fix release, which fixes security issues and 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/Werkzeug/3.1.5/ Changes: https://werkzeug.palletsprojects.com/page/changes/#version-3-1-5 Milestone: https://github.com/pallets/werkzeug/milestone/43?closed=1

• safe_join on Windows does not allow more special device names, regardless of extension or surrounding spaces. GHSA-87hc-h4r5-73f7
• The multipart form parser handles a \r\n sequence at a chunk boundary. This fixes the previous attempt, which caused incorrect content lengths. #3065 #3077
• Fix AttributeError when initializing DebuggedApplication with pin_security=False. #3075

3.1.4

This is the Werkzeug 3.1.4 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/Werkzeug/3.1.4/ Changes: https://werkzeug.palletsprojects.com/page/changes/#version-3-1-4 Milestone: https://github.com/pallets/werkzeug/milestone/42?closed=1

• safe_join on Windows does not allow special device names. This prevents reading from these when using send_from_directory. secure_filename already prevented writing to these. ghsa-hgf8-39gv-g3f2
• The debugger pin fails after 10 attempts instead of 11. #3020
• The multipart form parser handles a \r\n sequence at a chunk boundary. #3065
• Improve CPU usage during Watchdog reloader. #3054
• Request.json annotation is more accurate. #3067
• Traceback rendering handles when the line number is beyond the available source lines. #3044
• HTTPException.get_response annotation and doc better conveys the distinction between WSGI and sans-IO responses. #3056

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.
