GHSA-8PVW-JCV7-9CMJ @fastify/static vulnerable to Authorization Bypass via Non-Canonical URL Paths

Impact @fastify/static evaluates the allowedPath callback before normalizing dot segments and duplicate slashes in the pathname used for file resolution. Non-canonical pathnames such as //file, /./file, or /public/../private/file bypass allowedPath filtering while resolving to the intended file o...
