### GitHub Vulnerability Alerts

#### [CVE-2024-1135](https://nvd.nist.gov/vuln/detail/CVE-2024-1135)

Gunicorn fails to properly validate Transfer-Encoding headers, leading
to HTTP Request Smuggling (HRS) vulnerabilities. By crafting requests
with conflicting Transfer-Encoding headers, attackers can bypass
security restrictions and access restricted endpoints. This issue is due
to Gunicorn's handling of Transfer-Encoding headers, where it
incorrectly processes requests with multiple, conflicting
Transfer-Encoding headers, treating them as chunked regardless of the
final encoding specified. This vulnerability has been shown to allow
access to endpoints restricted by gunicorn. This issue has been
addressed in version 22.0.0.

To be affected users must have a network path which does not filter out
invalid requests. These users are advised to block access to restricted
endpoints via a firewall or other mechanism if they are unable to
update.

[`v22.0.0`](https://togithub.com/benoitc/gunicorn/releases/tag/22.0.0):
Gunicorn 22.0 has been released

[Compare

**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)
