CVE-2026-6414 · @fastify/static vulnerable to route guard bypass via encoded path separators

Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.

@fastify/static versions 8.0.0 through 9.1.0 decode percent-encoded path separators (%2F) before filesystem resolution, while Fastify's router treats them as literal characters. This mismatch allows attackers to bypass route-based middleware or guards that protect files served by @fastify/static. For example, a route guard on a protected path can be circumvented by encoding the path separator in the URL. Upgrade to @fastify/static 9.1.1 to fix this issue. There are no workarounds.
