Descriptions

@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.

@fastify/session es un complemento de sesión para fastify. Requiere el complemento @fastify/cookie. Al restaurar la cookie desde el almacén de sesiones, el campo "expires" se anula si se configuró el campo "maxAge". Esto significa que una cookie nunca se detecta correctamente como caducada y, por lo tanto, las sesiones caducadas no se destruyen. Esta vulnerabilidad ha sido parcheada 10.8.0.
