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.","categories":["Libraries & packages"],"product":"coraza","vendor":"corazawaf","ecosystem":"Go","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114099","source_modified_at":"2026-10-21T00:37:01.866Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"coraza","vendor":"corazawaf","versions":[{"version":"3.0.0","status":"affected","versionType":"semver","lessThan":"3.8.1"},{"version":"3.8.1","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-5gj4-9gm7-2fx2","source_modified_at":"2026-10-21T10:57:16.166426844Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v3","purl":"pkg:golang/github.com/corazawaf/coraza/v3"},"ranges":[{"events":[{"introduced":"3.0.0"},{"fixed":"3.8.1"}],"type":"SEMVER"}],"versions":[]}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114099","source_modified_at":"2026-10-21T00:37:01.866Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"coraza","ecosystem":null},"version":"3.8.1","basis":"first unaffected version stated in the CVE record"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-5gj4-9gm7-2fx2","source_modified_at":"2026-10-21T10:57:16.166426844Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v3","purl":"pkg:golang/github.com/corazawaf/coraza/v3"},"version":"3.8.1"}],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00198,"percentile":0.0912,"score_date":"2026-10-23"},"published_at":"2026-10-21T00:37:01.866Z","modified_at":"2026-10-21T10:57:16.166426844Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-114099","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T00:37:01.866Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-5gj4-9gm7-2fx2","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-21T10:57:16.166426844Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-114099","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-5gj4-9gm7-2fx2","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/coraza-3.0.0-before-3.8.1-waf-bypass-via-json-key-collision","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-21T10:57:16.166426844Z","content_hash":"79e1195ce65bc71ad32a5da161f75ade0b0a9da0472f6f680fa7c80a98ea03b9"}}
