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.

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)
