How broadly exploitable is this vulnerability?

Exploitability depends on an attacker's ability to obtain a valid transient access token. Once such a token is acquired, the vulnerability can typically be exploited remotely via the PMS API, without further user interaction.

What level of access does an attacker need to exploit this issue?

The attacker needs access to a valid transient token associated with a user's Plex account. This can arise from network interception on insecure channels, compromised devices or browsers, access to application logs, or other scenarios where transient tokens might be exposed.

What is the safest general fix pattern?

The safest approach is to redesign token handling so that transient tokens are strictly scoped, short-lived, and never accepted by endpoints that issue or reveal permanent or higher-privilege tokens. Each sensitive endpoint should verify token type and scope before returning any credential-like data.
