Plex Discloses Breach, Tells Users To Reset Passwords

The company has not said how many users were affected or which hashing method was used.

Overview

  • Plex says an unauthorized party accessed a limited subset of data in one database, including email addresses, usernames, hashed passwords, and unspecified authentication data.
  • Payment card details were not affected because Plex does not store them on its servers.
  • Users are instructed to reset passwords, sign out of all connected devices (or all sessions for SSO), and enable two-factor authentication.
  • Plex says it has fixed the access method used in the intrusion and is conducting additional security reviews, but it has not detailed the timeline or scope.
  • Reporting notes Plex is pushing Plex Media Server updates to version 1.42.1 with a fix for CVE-2025-34158, and some server access may be temporarily blocked until owners update.
