From 1.5.0 until 1.7.8, pkg/appsec/request.go NewParsedRequestFromRequest allocated a request body buffer from max(r.ContentLength, 0), so HTTP/1.1 requests using Transfer-Encoding: chunked and HTTP/2 requests without a content-length header produced an empty body and caused WAF rules targeting REQUEST_BODY, BODY_ARGS, ARGS_POST, JSON, or XML to be skipped. This issue is fixed in version 1.7.8."

      "value": "CrowdSec ofrece protección colaborativa contra IPs maliciosas. Desde la versión 1.5.0 hasta la 1.7.8, pkg/appsec/request.go NewParsedRequestFromRequest asignaba un búfer para el cuerpo de la solicitud a partir de max(r.ContentLength, 0), por lo que las solicitudes HTTP/1.1 que utilizaban Transfer-Encoding: chunked y las solicitudes HTTP/2 sin una cabecera content-length producían un cuerpo vacío y hacían que las reglas del WAF dirigidas a REQUEST_BODY, BODY_ARGS, ARGS_POST, JSON o XML fueran omitidas. Este problema está solucionado en la versión 1.7.8."
