CVE-2026-25949 · Traefik: TCP readTimeout bypass via STARTTLS on Postgres
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Traefik is an HTTP reverse proxy and load balancer. Prior to 3.6.8, there is a potential vulnerability in Traefik managing STARTTLS requests. An unauthenticated client can bypass Traefik entrypoint respondingTimeouts.readTimeout by sending the 8-byte Postgres SSLRequest (STARTTLS) prelude and then stalling, causing connections to remain open indefinitely, leading to a denial of service. This vulnerability is fixed in 3.6.8.
