Six Flaws Confirmed Under Active Attack, Now on CISA's Mandatory Patch List
In short: CISA has confirmed real-world exploitation of six vulnerabilities and placed them on its Known Exploited Vulnerabilities Catalog. Four of the six hit Plex Media Server, covering two SSRF bugs, a URI-scheme handling flaw and a file-path control issue; the remaining two are an OS command injection in EG Secure Solutions SiteGuard Server Edition and an uncontrolled search path flaw in Siemens Software Center. Because the flaws are already being exploited, Binding Operational Directive 26-04 forces federal civilian agencies to fast-track fixes on any exposed system that could hand attackers full control, and to check for prior compromise first.

What changed?
- 1Four Plex Media Server CVEs added: CVE-2026-96652 and CVE-2026-96655 (SSRF), CVE-2026-96654 (URI scheme handling), CVE-2026-96656 (file name/path control)
- 2CVE-2026-106931 added: OS command injection in EG Secure Solutions SiteGuard Server Edition
- 3CVE-2026-110936 added: uncontrolled search path element in Siemens Software Center
- 4CISA confirms all six are being actively exploited in the wild
- 5BOD 26-04 requires FCEB agencies to prioritize patching on publicly exposed, fully-compromisable assets and verify whether a breach occurred before the patch was applied
Why it matters
Active exploitation means attackers already have working techniques against these products, so any organization running Plex, SiteGuard, or Siemens Software Center is a live target, not a theoretical risk.
What it means for AI agents and contact centers
None of these products are part of a typical voice AI or telephony stack, so no direct exposure is expected; it's worth a quick check only if Plex, SiteGuard or Siemens Software Center happen to run anywhere on internal servers.
