CVE-2026-52845

Caddy is an extensible server platform that uses TLS by default. Prior to 2.11.4, forwardauth copyheaders deletes the exact client-supplied identity header before copying the trusted value from the auth gateway. But when the request later goes through phpfastcgi, Caddy normalizes HTTP headers int...

CVE-2026-45135

Caddy is an extensible server platform that uses TLS by default. From 2.7.0 until 2.11.3, the FastCGI transport's splitPos in modules/caddyhttp/reverseproxy/fastcgi/fastcgi.go misuses golang.org/x/text/search with search.IgnoreCase when the request path contains a non-ASCII byte. Two distinct fla...

CVE-2026-45135

CVE-2026-45135 (Caddy) describes two Unicode bypass flaws in the FastCGI splitPos logic (modules/caddyhttp/reverseproxy/fastcgi/fastcgi.go) that mis-use golang.org/x/text/search with IgnoreCase when a non-ASCII byte appears in the request path. This can cause a non-.php file to be treated as a sc...
