CVE-2026-71325 - Traefik: `allowCrossNamespace=false` bypass via `@kubernetescrd` TraefikService backendRef

CVE ID :CVE-2026-71325
Published : Aug. 6, 2026, 10:18 p.m. | 13 minutes ago
Description :Traefik is an open-source edge router that makes publishing services a fun and easy experience. Prior to 2.11.54, 3.6.25, and 3.7.10, cross-namespace @kubernetescrd references are not rejected for TraefikService backend references resolved by the service resolver. A tenant confined by RBAC to a single namespace can therefore bind its own router to a TraefikService owned by another namespace and expose or reroute that namespace's backend, defeating the namespace isolation allowCrossNamespace=false is meant to enforce. This issue is fixed in version 2.11.54, 3.6.25, 3.7.10.
Severity: 4.8 | MEDIUM
