CVE-2026-54765

CVE-2026-54765 affects Traefik v3.7.0 through v3.7.5, fixed in v3.7.6. In the Kubernetes Gateway API provider, two accepted HTTPRoutes targeting the same backend Service:port can have different backendRef filters, with only one route’s filter set applied to all requests. This can allow a route’s ...

CVE-2026-54765 Traefik: Gateway HTTPRoute backendRef filters can leak backend context across routes sharing a Service:port

Traefik is an open source HTTP reverse proxy and load balancer. From v3.7.0 prior to v3.7.6, Traefik's Kubernetes Gateway API provider may resolve two accepted HTTPRoutes that target the same backend Service:port but configure different backendRef filters to the same child service and apply only...

CVE-2026-54764

Traefik is an HTTP reverse proxy and load balancer. Prior to v2.11.51, v3.6.22, and v3.7.6, Traefik's ForwardAuth middleware, even when configured with trustForwardHeader: false, derives the X-Forwarded-Port header sent to the authentication service from the original incoming request instead of t...

CVE-2026-9545

A flaw was found in libcurl. An attacker can exploit this by replacing a legitimate HTTP/3 server with an impostor machine. When libcurl attempts a second transfer to the same site with a cached SSL session and early data enabled, it may send sensitive request data before verifying the server's...

CVE-2026-50134 Hugo: security.http.urls allow-list bypass via HTTP redirects

Hugo is a static site generator. From 0.91.0 until 0.162.0, resources.GetRemote enforces security.http.urls on the URL it is called with, but it did not re-validate intermediate URLs on HTTP 3xx redirects. An allowed server or an attacker controlling its DNS or response could therefore redirect t...

CVE-2026-58404 Hugo security.http.urls deny rules bypassed by alternate IPv4 encodings

Hugo is a static site generator. From v0.162.0 through v0.163.0, the default security.http.urls policy denies requests to loopback, internal, and cloud-metadata IPv4 literals, but the deny rule only matched dotted-decimal notation, so alternate IPv4 encodings of the same addresses, including...
