CVE-2026-52844Caddy: Windows `file_server` path authorization bypass via encoded backslash

caddyserver caddy Veröffentlicht: (vor 4 Monaten)

Beschreibung

Caddy is an extensible server platform that uses TLS by default. Prior to 2.11.4, on Windows, Caddy path matchers treat /private\secret.txt as outside /private/*, but file_server later resolves the same request path as private\secret.txt on disk. An unauthenticated remote client can bypass Caddy path-scoped auth/deny routes protecting /private/*. This vulnerability is fixed in 2.11.4.

Schwachstellentyp (CWE): CWE-22CWE-284
