What an attacker can do
The source says ### Summary Coraza fails to inspect URL-encoded form bodies when their valid `Content-Type` contains a media-type parameter, for example: ```http Content-Type: application/x-www-form-urlencoded; charset=UTF-8 ``` An unauthenticated attacker can use this header to hide the complete form body from custom Coraza rules that inspect `ARGS_POST` or `REQUEST_BODY`, while the bundled Go HTTP middleware forwards the body and the backend parses it normally. Source advisory’s CVSS 3.1 assessment rates confidentiality and availability impact as none; integrity impact as low.
