CVE-2024-35220

Estado: AplazadaAlta (7.4)—

@fastify/session is a session plugin for fastify. Requires the @fastify/cookie plugin. When restoring the cookie from the session store, the `expires` field is overriden if the `maxAge` field was set. This means a cookie is never correctly detected as expired and thus expired sessions are not destroyed. This vulnerability has been patched 10.8.0.
