Five actively exploited flaws demand immediate action: OS command injection in SiteGuard Server Edition, multiple critical vulnerabilities in Plex Media Server, uncontrolled DLL loading in Siemens Software Center, and authentication bypass in Oracle Access Manager.

High · CVSS 7.8Actively exploitedCVE-2026-106931

### [SiteGuard Server Edition OS command injection allows root/SYSTEM privilege escalation](https://securexion.com/cve-2026-106931/)

E-guardian SiteGuard Server Edition versions 2.20 through 8.00 contain an OS command injection vulnerability (CWE-78) exploitable by local users with low privileges. Attackers can execute arbitrary commands with root or SYSTEM level access, fully compromising the host system.

**What to do:** Immediately patch to version 8.00 or later; verify no unsupported versions (2.20–7.00) remain in production inventory.

High · CVSS 7.2Actively exploitedCVE-2026-96656, CVE-2026-96654, CVE-2026-96655, CVE-2026-96652

### [Plex Media Server multiple critical flaws enable file write, SSRF, and cross-plugin attack](https://securexion.com/cve-2026-96656/)

Plex Media Server before version 1.43.3.10861 contains four distinct actively exploited vulnerabilities including arbitrary file write (CWE-73), server-side request forgery via two endpoints (CWE-918), and URL-scheme mishandling (CWE-84). Together, these allow admin users to achieve code execution, authenticated users to perform SSRF attacks, and unauthenticated users to manipulate plugin behavior.

**What to do:** Immediately patch all Plex Media Server instances to version 1.43.3.10861 or later; verify no instances remain on pre-1.43.3.10861 versions.

High · CVSS 6.7Actively exploitedCVE-2026-110936

### [Siemens Software Center uncontrolled DLL load enables local privilege escalation](https://securexion.com/cve-2026-110936/)

Siemens Software Center before version 4.0.9.8 searches for dynamic-link libraries (DLLs) in uncontrolled paths, allowing an authenticated local attacker to plant a malicious DLL and achieve code execution with the application's privileges. This is actively exploited.

**What to do:** Patch Siemens Software Center to version 4.0.9.8 or later immediately; audit all versions prior to 4.0.9.8 in your environment.

Critical · CVSS 10CVE-2026-87337

### [Oracle Access Manager authentication bypass allows unauthenticated compromise](https://securexion.com/cve-2026-87337/)

Oracle Access Manager versions 12.2.1.4.0 and 14.1.2.1.0 contain an easily exploitable vulnerability in the Authentication Engine component that allows unauthenticated network attackers to gain full control. This is a CVSS 10.0 flaw with scope change affecting the entire platform.

**What to do:** Immediately apply Oracle's security patch to Access Manager 12.2.1.4.0 or 14.1.2.1.0; upgrade to a patched version or discontinue use if patches are unavailable.
