description

Plex Media Server versions before 1.43.3.10861 are affected by a server-side request forgery flaw. An authenticated attacker may cause the server to send requests to attacker-selected internal or external network addresses. Exploitation requires valid access to the server.

mitigation

Upgrade Plex Media Server to version 1.43.3.10861 or later. Limit authenticated access to trusted users until the update is complete.

fixed in 1.43.3.10861
