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.","cvssScore":5.8,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","cwes":["CWE-20"],"vendors":[],"products":[],"references":[{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-5gj4-9gm7-2fx2","tags":[]},{"url":"https://www.vulncheck.com/advisories/coraza-3.0.0-before-3.8.1-waf-bypass-via-json-key-collision","tags":[]}],"exploitRefs":[{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-5gj4-9gm7-2fx2","tags":[]}],"hasPoc":true,"ai":null}
