CVE-2026-88878

A flaw was found in Traefik, an HTTP reverse proxy and load balancer. When HTTP/3 is enabled, an unauthenticated remote client can exploit a timeout bypass vulnerability by trickling request body bytes. This allows the client to hold a request open indefinitely, exhausting backend connection pool...

CVE-2026-88878

Traefik (HTTP reverse proxy and load balancer) versions v2.8.2 through v2.11.55 and v3.0.0 through v3.7.11 are affected by an HTTP/3 timeout bypass. The respondingTimeouts settings (notably readTimeout, default 60s) are not applied to the HTTP/3 request path because readTimeout is enforced as a d...
