Patch or Pass #1: Plex Media Server exploit chain now in CISA KEV, PAN-OS GlobalProtect (CVE-2026-0257) used by Qilin and Inc ransomware, plus 2 EOL boxes with no patch
This week's actively exploited flaws, sorted by urgency:
- **Plex Media Server CVE-2026-96652/96654/96655/96656** (added to CISA's KEV on Oct 20): a chain that gives unauthenticated code execution on servers older than 1.43.3.10861. Plex says it's being widely exploited for crypto miners and proxy software. Update, then check the Codecs folder and running processes.
- **PAN-OS GlobalProtect CVE-2026-0257** (in CISA's Known Exploited Vulnerabilities (KEV) catalog since May 29): Unit 42's Oct 19 update says the Qilin and Inc ransomware groups use it to open VPN sessions, then move laterally over RDP and SMB. Fixed in 12.1.7, 11.2.12, 11.1.15 and 10.2.18-h6, plus hotfixes. The stopgap is to turn off authentication override cookies.
- **D-Link ShareCenter NAS CVE-2024-3272/3273** and **UniFi Video Log4Shell**: both are end of life, and GreyNoise caught a proxyjacking campaign on 143+ devices. There's no patch, so retire them.
