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

Sourced from flask's changelog.

Version 3.1.3

Released 2026-02-18

• 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

Version 3.1.2

Released 2025-08-19

• stream_with_context does not fail inside async views. :issue:5774
• When using follow_redirects in the test client, the final state of session is correct. :issue:5786

Version 3.1.1

Released 2025-05-13

• 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. :issue:5645
• flask --help loads the app and plugins first to make sure all commands are shown. :issue: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. :pr:5659

Version 3.1.0

Released 2024-11-13

• Drop support for Python 3.8. :pr:5623
• Update minimum dependency versions to latest feature releases. Werkzeug >= 3.1, ItsDangerous >= 2.2, Blinker >= 1.9. :pr:5624,5633

• 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. :issue:5504

4.1.1

Bug Fix

• Ensure cli commands fail gracefully when cli dependencies are not installed.

Sourced from flask-limiter's changelog.

v4.1.1

Release Date: 2025-12-06

• Bug Fix

  • Ensure cli commands fail gracefully when cli dependencies are not installed.

v4.1.0

Release Date: 2025-12-02

• Deployment

  • Extract cli specific requirements to an extra

• Compatibility

  • Add python 3.14 support

v4.0.0

Release Date: 2025-09-30

• Feature

  • Expose flask_limiter.Limit, flask_limiter.RouteLimit, flask_limiter.ApplicationLimit & flask_limiter.MetaLimit limit description classes that can be used to pass in default, application & meta limits to the Limiter extension. This allows for a more fine grained control for end users while also simplifying the internal implementation of different types of limits.

• Compatibility

  • Prefix all internal sub modules with underscore. All imports should be from the root flask_limiter namespace only.

• Development

  • Migrate all project metadata to pyproject
  • Remove versioneer
  • Use uv for development
  • Use hatch for build

26.0.0

Breaking Changes

• Eventlet worker removed: The eventlet worker class has been dropped. Migrate to gevent, gthread, or tornado.

New Features

• ASGI Framework Compatibility Suite: New end-to-end compatibility test harness covering Starlette, FastAPI, Litestar, Quart, Sanic, and BlackSheep. Current grid passes 438/444 tests (98%).
• ASGI Test Suite Expansion: 134 additional ASGI unit tests covering protocol semantics, lifespan, websockets, and chunked framing.

Security

• HTTP/1.1 Request-Target Validation (RFC 9112 sections 3.2.3, 3.2.4):
  • Reject authority-form request-target outside CONNECT
  • Reject asterisk-form request-target outside OPTIONS
  • Reject relative-reference request-targets
• Header Field Hardening (RFC 9110):
  • Reject control characters in header field-value (section 5.5)
  • Reject forbidden trailer field-names (section 6.5.1)
  • Reject Content-Length list form (RFC 9112 section 6.3)
• Request Smuggling Hardening:
  • Tighten keepalive gate and scope finish_body byte cap
  • Keep _body_receiver alive across the keepalive smuggling gate so pipelined requests cannot re-enter a closed body
  • Address parser/protocol findings from a six-point WSGI/ASGI audit
• PROXY Protocol (ASGI): Enforce proxy_allow_ips and tighten v1/v2 parsing in the ASGI callback parser.
• Connection Draining: Drain the connection on close per RFC 9112 section 9.6 to prevent reset-on-close truncation.

Bug Fixes

• Body Framing on HEAD/204/304:
  • Keep Content-Length on HEAD and 304 responses (#3621)
  • Drop body framing on HEAD/204/304 even when the framework set it
  • Warn once when an ASGI app emits a body for a no-body response
• HTTP/2 ASGI:
  • Fix _handle_stream_ended to set _body_complete in the async HTTP/2 handler so request bodies finalize correctly on stream end
  • Add InvalidChunkExtension mapping and fast-parser support in ASGI tests (#3565)
• HTTP/1.1 100-Continue: Stop adding Transfer-Encoding: chunked to 100-Continue interim responses.
• WebSocket Close Handshake (RFC 6455):
  • Comply with the close handshake state machine
  • Close the transport after the close handshake completes
  • Fix binary send when the text key is None
• Early Hints: Validate headers in the early_hints callback to match process_headers; pass only the header name to InvalidHeader (#3588).
• ASGI Framework Fixes:
  • Fix ASGI disconnect handling for Django-style apps
  • Fix Litestar request handling (use raw ASGI receive for body/headers)
  • Fix Litestar HTTP endpoints for compatibility tests
  • Fix Quart headers endpoint to normalize keys to lowercase
  • Fix Quart WebSocket close test app (missing accept())
  • Fix duplicate Transfer-Encoding header for BlackSheep streaming
