Name of the Vulnerable Software and Affected Versions @fastify/static versions prior to 10.1.1 Description An unauthenticated attacker can bypass route-scoped middleware and guards by using non-leading .. and %2E%2E path segments in request pathnames. This occurs because the find-my-way router do...

PT-2026-63567

Name of the Vulnerable Software and Affected Versions @fastify/static versions prior to 10.1.2 Description An unauthenticated attacker can bypass path-based filtering because the allowedPath callback is evaluated before the normalization of dot segments and duplicate path separators in the pathna...
