Vulnerability from github – Published: 2025-08-29 20:08 – Updated: 2025-11-04 16:22

Summary

Eventlet affected by HTTP request smuggling in unparsed trailers

Details

Impact

The Eventlet WSGI parser is vulnerable to HTTP Request Smuggling due to improper handling of HTTP trailer sections.

This vulnerability could enable attackers to: - Bypass front-end security controls - Launch targeted attacks against active site users - Poison web caches

Patches

Problem has been patched in eventlet 0.40.3.

The patch just drops trailers. If a backend behind eventlet.wsgi proxy requires trailers, then this patch BREAKS your setup.

Workarounds

Do not use eventlet.wsgi facing untrusted clients.

Vulnerability from cvelistv5 – Published: 2025-08-29 21:12 – Updated: 2025-11-03 18:13

Summary

Eventlet is a concurrent networking library for Python. Prior to version 0.40.3, the Eventlet WSGI parser is vulnerable to HTTP Request Smuggling due to improper handling of HTTP trailer sections. This vulnerability could enable attackers to, bypass front-end security controls, launch targeted attacks against active site users, and poison web caches. This problem has been patched in Eventlet 0.40.3 by dropping trailers which is a breaking change if a backend behind eventlet.wsgi proxy requires trailers. A workaround involves not using eventlet.wsgi facing untrusted clients.
