When an Ingress path uses a regex that captures attacker-controlled text without requiring a path separator (e.g., path /api(.*) with rewrite target /$1), a crafted request such as /api../admin matches the public router, is rewritten to a dot-segment traversal path (/../admin), and is forwarded without post-replacement normalization validation. A backend that normalizes dot segments resolves the path to a protected endpoint (e.g., /admin) reachable only through a separate router secured with BasicAuth, DigestAuth, or ForwardAuth, resulting in route-level authentication bypass. The issue is fixed in v3.7.8.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N","score":7.8,"severity":null}],"references":["https://github.com/traefik/traefik/security/advisories/GHSA-8rxv-jg7p-wvg3","https://github.com/traefik/traefik/commit/b93f02cd07b79490fb8c8f02e301a7a1ec553195","https://github.com/traefik/traefik/commit/69259c3acc9d4bdc065cb2e3b83336f7de3e7038","https://www.vulncheck.com/advisories/traefik-path-traversal-via-rewritetarget-authentication-bypass"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-51815","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 1, 2026, 12:22:18 PM","dateUpdated":"Oct 8, 2026, 3:24:04 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
