CVE-2025-11699 is a session management vulnerability in nopCommerce affecting version 4.70 and prior, and version 4.80.3. The application does not properly invalidate session cookies after user logout or session termination. As a result, a previously issued valid session cookie can remain usable and continue to authorize access to privileged application endpoints, including administrative paths such as /admin, even after the legitimate user has logged out. This creates a post-logout session hijacking condition in which possession of a valid session token is sufficient to continue an authenticated session.
