Unauthenticated attackers can send application/x-www-form-urlencoded; charset=UTF-8 to keep ARGS_POST and REQUEST_BODY empty, evading body rules while the backend still processes the payload.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","score":5.8},"cwes":["CWE-20"],"references":["https://github.com/corazawaf/coraza/security/advisories/GHSA-w253-m66g-rx24","https://www.vulncheck.com/advisories/coraza-from-3.0.4-before-3.8.1-request-body-inspection-bypass-via-content-type"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-114100","score":0.00282,"percentile":0.20523,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-w253-m66g-rx24","url":"https://osv.dev/vulnerability/GHSA-w253-m66g-rx24","summary":"Coraza: URL-encoded form Content-Type parameters bypass Coraza body inspection","modified":"2026-10-21T10:56:44.870639532Z","packages":[{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v3","purl":"pkg:golang/github.com/corazawaf/coraza/v3","ranges":[">=3.0.4 <3.8.1"],"fixed":["3.8.1"]}]},{"id":"GO-2026-6698","url":"https://osv.dev/vulnerability/GO-2026-6698","summary":"Coraza: URL-encoded form Content-Type parameters bypass Coraza body inspection in github.com/corazawaf/coraza","modified":"2026-10-21T10:56:44.870639532Z","packages":[{"ecosystem":"Go","name":"github.com/corazawaf/coraza","purl":"pkg:golang/github.com/corazawaf/coraza","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v2","purl":"pkg:golang/github.com/corazawaf/coraza/v2","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v3","purl":"pkg:golang/github.com/corazawaf/coraza/v3","ranges":[">=3.0.4 <3.8.1"],"fixed":["3.8.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
