properties that are required to process the data safely and
correctly. Impacted is integrity. CVE summarizes:
Coraza from 3.0.4 before 3.8.1 contains a request body inspection bypass because request-body processor selection compares the entire Content-Type value exactly, so URL-encoded bodies whose Content-Type carries a media-type parameter are never parsed. Unauthenticated attackers can send application/x-www-form-urlencoded; charset=UTF-8 to keep ARGS_POST and REQUEST_BODY empty, evading body rules while the backend still processes the payload.
The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-114100 since 10/20/2026. The exploitation is known to be easy. The attack may be launched remotely.
