Description

Traefik before v2.11.58 and v3.7.14 contains an authentication bypass vulnerability in its SNI check, which is skipped when request TLS state is nil. Unauthenticated clients can send HTTP/2 requests with the :scheme http pseudo-header over TLS on Go 1.27 builds to reach routers requiring client certificates without presenting one.

Affected configurations

• traefik traefik (< 2.11.58) • traefik traefik (>= 3.0.0 < 3.7.14)
