Kerentanan Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') pada caddyserver caddy. Skor CVSS 3.1 7.5 (High) menurut github.com.

Deskripsi (NVD)

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.
