CVE-2026-114099 · Coraza 3.0.0 before 3.8.1 WAF Bypass via JSON Key Collision
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Coraza from 3.0.0 before 3.8.1 has a JSON body processor that flattens nested properties into dot-separated ARGS_POST names without escaping literal dots, so distinct properties collide. Unauthenticated attackers can add a later dotted property such as account.role that overwrites a malicious nested value, hiding SQL injection payloads from OWASP CRS rules while backends still receive them.
