Vulnerability Title
@fastify/session reuses destroyed session cookie
Source: CVE Program / CVE List V5
Vulnerability Description
@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.
