CVE-2025-69417
📋 TL;DR
This vulnerability allows a non-server device token to retrieve share tokens intended for unrelated access via the shared_servers endpoint in Plex Media Server. This affects Plex Media Server users with shared server access enabled. The issue could allow unauthorized access to shared media content.
💻 Affected Systems
- Plex Media Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could gain unauthorized access to all shared media libraries across multiple Plex servers, potentially exposing private media content.
Likely Case
Limited unauthorized access to some shared media content that the attacker shouldn't have permission to view.
If Mitigated
Minimal impact if proper access controls and network segmentation are in place, limiting exposure to authorized users only.
🎯 Exploit Status
Exploitation requires a valid non-server device token and knowledge of the shared_servers endpoint. No public exploit code is available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not yet released
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Monitor Plex security advisories for updates. 2. Apply patches when available from official Plex channels. 3. The fix will likely require backend updates from Plex.
🔧 Temporary Workarounds
Disable Server Sharing
allTemporarily disable Plex server sharing functionality to prevent exploitation
Navigate to Settings > Server > Remote Access > Disable Remote Access
Network Segmentation
allRestrict Plex server access to trusted networks only
Configure firewall rules to limit Plex server access to internal networks
🧯 If You Can't Patch
- Implement strict access controls and monitor for unusual share token requests
- Consider using VPN for remote Plex access instead of direct internet exposure
🔍 How to Verify
Check if Vulnerable:
Check if your Plex Media Server version is affected by comparing against the vulnerable version range
Check Version:
Check Plex Media Server version in Settings > Server > General
Verify Fix Applied:
Verify that share tokens cannot be retrieved by non-server device tokens after patching
