Description

Tautulli is a Python based monitoring and tracking tool for Plex Media Server. From version 2.14.2 to before version 2.17.0 for parameters "before" and "after" and from version 2.1.0-beta to before version 2.17.0 for parameters "section_id" and "user_id", the /api/v2?cmd=get_home_stats endpoint passes the section_id, user_id, before, and after query parameters directly into SQL via Python %-string formatting without parameterization. An attacker who holds the Tautulli admin API key can inject arbitrary SQL and exfiltrate any value from the Tautulli SQLite database via boolean-blind inference. This issue has been patched in version 2.17.0.

Tautulli: from 2.1.0 before 2.17.0 — fixed in 2.17.0
