This link is maintained to preserve external references.\n\n## Original Description\nTraefik 3.6.0 through 3.6.22 and 3.7.0 through 3.7.6 fail to enforce the crossProviderNamespaces allowlist for IngressRouteTCP service serversTransport references (the allowlist was only enforced for HTTP serversTransport references). A low-privileged Kubernetes user in a namespace not listed in crossProviderNamespaces can set serversTransport: foo@file on an IngressRouteTCP service, causing Traefik to accept the forbidden cross-provider reference and use a file-provider TCPServersTransport — including privileged backend mTLS client certificates, SPIFFE identity, or PROXY-protocol settings. This is fixed in 3.6.23 and 3.7.7.","public_affected_ranges":[">= 3.6.0, <= 3.6.22"]}],"null_published_at":"2026-11-03T10:03:26.560Z","source_updated_at":"2026-08-05T21:51:08.000Z","source_disclosed_at":"2026-07-22T12:32:18.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-03T02:28:46.523Z"}],"next_cursor":null,"snapshot_revision":"42594"}
