NVD Description

Note: Versions mentioned in the description apply only to the upstream haproxy package and not the haproxy package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

HAProxy through 2.0.32, 2.1.x and 2.2.x through 2.2.30, 2.3.x and 2.4.x through 2.4.23, 2.5.x and 2.6.x before 2.6.15, 2.7.x before 2.7.10, and 2.8.x before 2.8.2 forwards empty Content-Length headers, violating RFC 9110 section 8.6. In uncommon cases, an HTTP/1 server behind HAProxy may interpret the payload as an extra request.
