AI-suggested
This vulnerability is fixed in Caddy version 2.11.4. Users should upgrade to version 2.11.4 or later to remediate this issue. No other mitigation or temporary workaround is indicated in the available data.
Description
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.
