CVE-2026-44774

A flaw was found in Traefik. A low-privileged tenant with HTTPRoute creation permissions in Traefik's Kubernetes Gateway API provider can bypass security settings. This allows the tenant to expose the REST provider handler and gain live dynamic configuration write access to Traefik. This vulnerability enables unauthorized reconfiguration of routers and services, potentially leading to privilege escalation within the system.
