Description
Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to 2.17.2, the newsletter cron field stored in the newsletters table is inserted by data/interfaces/default/newsletter_config.html into a JavaScript string without safe JSON encoding. An administrator or caller with the Tautulli API key can store a crafted cron value, and an administrator who later opens the newsletter configuration modal passively triggers script execution in the Tautulli web context. The stored value persists in the database and can continue to execute after credential rotation until it is removed. This issue is fixed in version 2.17.2.
