NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup-2_4-1 package and not the libsoup-2_4-1 package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

A request smuggling vulnerability exists in libsoup's HTTP/1 header parsing logic. The soup_message_headers_append_common() function in libsoup/soup-message-headers.c unconditionally appends each header value without validating for duplicate or conflicting Content-Length fields. This allows an attacker to send HTTP requests containing multiple Content-Length headers with differing values.
