CVE-2026-31831 identifies a high-severity path traversal vulnerability in Tautulli, a Plex Media Server monitoring tool, affecting versions prior to 2.17.0. Rated 8.7 CVSS, this flaw allows unauthenticated attackers to remotely read arbitrary files from the application server's filesystem with low attack complexity and no user interaction. The potential impact is high confidentiality compromise through sensitive data disclosure. Currently, there is no public exploit code available, nor is it listed on the CISA KEV catalog, and its EPSS score indicates a very low probability of exploitation. While community discussion is minimal, patching to version 2.17.0 or later is crucial for mitigation.
