Administrative access via stale session trust
Published Jun 8, 2026 · Updated Jun 8, 2026
Improper authorization in Bludit before 3.22.0 allows remote authenticated users with retained sessions to regain administrative access. The isLogged() method in bl-kernel/login.class.php trusts the session username after fingerprint validation without checking whether the user still exists or is disabled. Exploitation requires a session established before account deletion or disablement; the retained role can publish content or create a replacement administrator account.
