Description

A flaw was found in @fastify/static. A remote attacker can exploit this vulnerability by sending specially crafted requests that include percent-encoded path separators. This mismatch in how @fastify/static decodes these separators compared to the Fastify router allows the attacker to bypass security measures such as route-based middleware or guards. Consequently, this can lead to unauthorized access to protected files or information disclosure.
