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
