Bumps gunicorn from 22.0.0 to 25.3.0.

Release notes

Sourced from gunicorn's releases.

Gunicorn 25.3.0

Bug Fixes

• HTTP/2 ASGI Body Duplication: Fix request body being received twice in HTTP/2 ASGI requests, causing JSON parsing errors with "Extra data" messages (#3558)

• ASGI Chunked EOF Handling: Add finish() method to callback parser to handle chunked encoding edge case where connection closes before final CRLF after zero-chunk

• HTTP/2 Documentation: Fix http_protocols examples to use comma-separated string instead of list syntax (#3561)

• Chunked Encoding: Reject chunk extensions containing bare CR bytes per RFC 9112 (#3556)

• Request Line Limit: Fix --limit-request-line 0 to mean unlimited as documented, instead of using default maximum. Works with both Python and fast C parser. (#3563)

Security

• ASGI Parser Header Validation: Add security checks per RFC 9110/9112:
  • Reject duplicate Content-Length headers
  • Reject requests with both Content-Length and Transfer-Encoding
  • Reject chunked transfer encoding in HTTP/1.0
  • Reject stacked chunked encoding
  • Validate Transfer-Encoding values
  • Strict chunk size validation

Changes

• Fast HTTP Parser: Update to gunicorn_h1c >= 0.6.3 for asgi_headers property and InvalidChunkExtension validation for bare CR rejection

• ASGI PROXY Protocol: Add PROXY protocol v1/v2 support to callback parser

• Docker Images: Update to Python 3.14

Gunicorn 25.2.0

New Features

• Fast HTTP Parser (gunicorn_h1c 0.4.1): Integrate new exception types and limit parameters from gunicorn_h1c 0.4.1 for both WSGI and ASGI workers
  • Requires gunicorn_h1c >= 0.4.1 for http_parser='fast'
  • Falls back to Python parser in auto mode if version not met
  • Proper HTTP status codes for limit errors (414, 431)

Bug Fixes

• uWSGI Async Workers: Fix InvalidUWSGIHeader: incomplete header error when using gevent or gthread workers with uwsgi protocol behind nginx. (#3552, [PR #3554](benoitc/gunicorn#3554))

PR Summary

Low Risk
Low-risk dependency bump, but it changes the production WSGI server version and could affect runtime behavior if deployment relies on Gunicorn-specific defaults or worker settings.

Overview
Updates the gunicorn dependency in requirements.txt from 22.0.0 to 25.3.0.

Lock files not updated, CI will fail

Medium Severity

requirements.txt bumps gunicorn to 25.3.0 but both requirements.lock and requirements-dev.lock still pin gunicorn==22.0.0. The CI workflow checks that lock files are updated whenever requirements.txt changes and will exit 1 if they diverge. Even if merged, CI installs from requirements-dev.lock, so the upgrade would have no effect in practice — production would still run gunicorn 22.0.0.

Superseded by #21 (deps: batched major-version updates). All four majors are now on main; this PR is redundant.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
