@fastify/static vulnerable to route guard bypass via encoded path separators

Impact @fastify/static v9.1.0 and earlier decodes percent-encoded path separators %2F before filesystem resolution, but Fastify's router treats them as literal characters. This creates a routing mismatch: route guards on /admin/ do not match /admin%2Fsecret.html, but @fastify/static decodes it to...

CVE-2026-6414

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...

CVE-2026-6410

A flaw was found in @fastify/static. When directory listing is enabled, a remote unauthenticated attacker can exploit a path traversal vulnerability. This occurs because the dirList.path function incorrectly resolves directories outside the configured static root. Successful exploitation allows t...
