Prior to 2.11.46, 3.6.17, and 3.7.1, Traefik's Kubernetes Gateway API provider allows a tenant with HTTPRoute creation permissions to expose the REST provider handler, bypassing the providers.rest.insecure=false setting. The Gateway provider accepts any TraefikService backend reference whose name ends with @internal, making it possible to route traffic to rest@internal in addition to the intended api@internal. In shared Gateway deployments where the REST provider is enabled, this allows a low-privileged actor to gain live dynamic configuration write access to Traefik, enabling unauthorized reconfiguration of routers and services. This vulnerability is fixed in 2.11.46, 3.6.17, and 3.7.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:H/SA:H","score":6.4},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9},"cwes":["CWE-284","CWE-15"],"references":["https://github.com/traefik/traefik/releases/tag/v2.11.46","https://github.com/traefik/traefik/releases/tag/v3.6.17","https://github.com/traefik/traefik/releases/tag/v3.7.1","https://github.com/traefik/traefik/security/advisories/GHSA-96qj-4jj5-wcjc","https://access.redhat.com/errata/RHSA-2026:36820"],"products":["traefik:traefik"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-44774","score":0.00468,"percentile":0.40499,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-96qj-4jj5-wcjc","url":"https://osv.dev/vulnerability/GHSA-96qj-4jj5-wcjc","summary":"Traefik: Gateway API TraefikService backend accepts rest@internal, allowing unauthorized exposure of the REST provider despite providers.rest.insecure=false","modified":"2026-06-25T19:56:08.468464561Z","packages":[{"ecosystem":"Go","name":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","ranges":[">=3.7.0 <3.7.1"],"fixed":["3.7.1"]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","ranges":["<3.6.17"],"fixed":["3.6.17"]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","ranges":["<2.11.46"],"fixed":["2.11.46"]},{"ecosystem":"Go","name":"github.com/traefik/traefik","purl":"pkg:golang/github.com/traefik/traefik","ranges":["<=1.7.34"],"fixed":[]}]},{"id":"GO-2026-5277","url":"https://osv.dev/vulnerability/GO-2026-5277","summary":"Traefik: Gateway API TraefikService backend accepts rest@internal, allowing unauthorized exposure of the REST provider despite providers.rest.insecure=false in github.com/traefik/traefik","modified":"2026-06-25T19:45:23.211459667Z","packages":[{"ecosystem":"Go","name":"github.com/traefik/traefik","purl":"pkg:golang/github.com/traefik/traefik","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","ranges":["<2.11.46"],"fixed":["2.11.46"]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","ranges":["<3.6.17",">=3.7.0 <3.7.1"],"fixed":["3.6.17","3.7.1"]}]}],"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).
