Description

Plex Media Server (PMS) 1.41.7.x through 1.42.0.x before 1.42.1 is affected by incorrect resource transfer between spheres because /myplex/account provides the credentials of the server owner (and a /api/resources call reveals other servers accessible by that server owner).

Incorrect Resource Transfer Between Spheres

The product does not properly transfer a resource/behavior to another sphere, or improperly imports a resource/behavior from another sphere, in a manner that provides unintended control over that resource.
