Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
AdminNeo versions before 5.5.1 have a CSRF protection weakness: each token carries both the XOR mask and the masked value, so anyone who sees a single token can recover the session secret and forge valid tokens. The source describes observation routes such as referrer leaks, logs, network sniffing, or XSS, and also says the session token has low entropy that could allow brute force. An attacker who can forge tokens can perform state-changing requests as a logged-in user, including SQL actions through AdminNeo. The fix is to upgrade to version 5.5.1.
