When another Ingress declares a path on the same host without matching auth-tls settings, Traefik falls back to default TLS options, letting unauthenticated attackers reach backends requiring client certificates.","cvssScore":8.7,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:N","cwes":["CWE-287"],"vendors":[],"products":[],"references":[{"url":"https://github.com/traefik/traefik/security/advisories/GHSA-p8wx-ph99-xgcr","tags":[]},{"url":"https://www.vulncheck.com/advisories/traefik-3.7.0-ea.1-before-3.7.15-mtls-bypass-via-ingress-nginx-provider","tags":[]}],"exploitRefs":[{"url":"https://github.com/traefik/traefik/security/advisories/GHSA-p8wx-ph99-xgcr","tags":[]}],"hasPoc":true,"ai":null}
