Release Notes

benoitc/gunicorn (gunicorn)

v24.1.1

Compare Source

Bug Fixes

• Fix forwarded_allow_ips and proxy_allow_ips to remain as strings for backward
  compatibility with external tools like uvicorn. Network validation now uses strict
  mode to detect invalid CIDR notation (e.g., 192.168.1.1/24 where host bits are set)

  PR #​3459)

v24.1.0: Gunicorn 24.1.0

Compare Source

New Features

• Official Docker Image: Gunicorn now publishes official Docker images to GitHub Container Registry (PR #​3454)

  • Available at ghcr.io/benoitc/gunicorn
  • Based on Python 3.12 slim image
  • Uses recommended worker formula (2 × CPU + 1)
  • Configurable via environment variables

• PROXY Protocol v2 Support: Extended PROXY protocol implementation to support the binary v2 format in addition to the existing text-based v1 format (PR #​3451)

  • New --proxy-protocol modes: off, v1, v2, auto
  • auto mode (default when enabled) detects v1 or v2 automatically
  • v2 binary format is more efficient and supports additional metadata
  • Works with HAProxy, AWS NLB/ALB, and other PROXY protocol v2 sources

• CIDR Network Support: --forwarded-allow-ips and --proxy-allow-from now accept CIDR notation (e.g., 192.168.0.0/16) for specifying trusted networks (PR #​3449)

• Socket Backlog Metric: New gunicorn.socket.backlog gauge metric reports the current socket backlog size on Linux systems (PR #​3450)

• InotifyReloader Enhancement: The inotify-based reloader now watches newly imported modules, not just those loaded at startup (PR #​3447)

Bug Fixes

• Fix signal handling regression where SIGCLD alias caused "Unhandled signal: cld" errors on Linux when workers fail during boot (#​3453)
• Fix socket blocking mode on keepalive connections preventing SSL handshake failures with async workers (PR #​3452)
• Use smaller buffer size in finish_body() for faster timeout detection on slow or abandoned connections (PR #​3453)
• Handle SSLWantReadError in finish_body() to prevent worker hangs during SSL renegotiation (PR #​3448)
• Log SIGTERM as info level instead of warning to reduce noise in orchestrated environments (PR #​3446)
• Print exception details to stderr when worker fails to boot (PR #​3443)
• Fix unreader.unread() to prepend data to buffer instead of appending (PR #​3442)
• Prevent RecursionError when pickling Config objects (PR #​3441)
• Use proper exception chaining with raise from in glogging.py (PR #​3440)

v23.0.0

Compare Source

Gunicorn 23.0.0 has been released. This version improve HTTP 1.1. support and which improve safety

You're invited to upgrade asap your own installation.

23.0.0 - 2024-08-10

• minor docs fixes (:pr:3217, :pr:3089, :pr:3167)
• worker_class parameter accepts a class (:pr:3079)
• fix deadlock if request terminated during chunked parsing (:pr:2688)
• permit receiving Transfer-Encodings: compress, deflate, gzip (:pr:3261)
• permit Transfer-Encoding headers specifying multiple encodings. note: no parameters, still (:pr:3261)
• sdist generation now explicitly excludes sphinx build folder (:pr:3257)
• decode bytes-typed status (as can be passed by gevent) as utf-8 instead of raising TypeError (:pr:2336)
• raise correct Exception when encounting invalid chunked requests (:pr:3258)
• the SCRIPT_NAME and PATH_INFO headers, when received from allowed forwarders, are no longer restricted for containing an underscore (:pr:3192)
• include IPv6 loopback address [::1] in default for :ref:forwarded-allow-ips and :ref:proxy-allow-ips (:pr:3192)

** NOTE **

• The SCRIPT_NAME change mitigates a regression that appeared first in the 22.0.0 release
• Review your :ref:forwarded-allow-ips setting if you are still not seeing the SCRIPT_NAME transmitted
• Review your :ref:forwarder-headers setting if you are missing headers after upgrading from a version prior to 22.0.0

** Breaking changes **

• refuse requests where the uri field is empty (:pr:3255)
• refuse requests with invalid CR/LR/NUL in heade field values (:pr:3253)
• remove temporary --tolerate-dangerous-framing switch from 22.0 (:pr:3260)
• If any of the breaking changes affect you, be aware that now refused requests can post a security problem, especially so in setups involving request pipe-lining and/or proxies.

Fix CVE-2024-1135

v22.0.0: Gunicorn 22.0 has been released

Compare Source

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 **
