On KEV
Description
Caddy is an extensible server platform that uses TLS by default. In version 2.11.3 and earlier, in modules/caddyhttp/fileserver/staticfiles.go, fileHidden() uses case-sensitive filepath.Match checks, so case variants can bypass hide rules on case-insensitive filesystems or when mixed-case paths coexist and expose files intended to be hidden.
