NVD Description
Note: Versions mentioned in the description apply only to the upstream caddy package and not the caddy package as distributed by Minimos.
See How to fix? for Minimos:latest relevant fixed versions and status.
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.
