Plex KEV ×4

Plex · Media Server · added October 20, 2026

Plex Media Server does not publish GitHub releases. plexinc/pms-docker is the Docker packaging repository, not the server changelog, so this pipeline does not read it. KEV matching still runs. Compare the version you have with Plex's own announcements.

Required action. Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.
