caddy: Caddy is an extensible server platform that uses TLS by default
CVE-2026-52844 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-52844, released June 23, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
