Plex Media Server versions before 1.43.3.10861 contain a path traversal vulnerability in the media retrieval endpoint. The server constructs a filesystem path from the url parameter without validating parent-directory traversal sequences. A remote attacker with a valid session token, or a LAN-adjacent attacker supplying a spoofed X-Forwarded-For header, can read arbitrary files accessible to the operating-system account running Plex Media Server. Exposed data can include the PlexOnlineToken, whose theft enables control of the Plex account and server.
