Summary

@fastify/static vulnerable to Authorization Bypass via Non-Canonical URL Paths

Details

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 on disk.

Applications that use allowedPath as a security boundary to restrict access to specific static files or path subtrees may unintentionally expose files that were intended to be denied.

Patches

Upgrade to @fastify/static >= 10.1.2.

Workarounds

None. Upgrade to the patched version.
