# CVE-2026-110936: Siemens Software Center Uncontrolled Search Path Element Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Siemens Software Center. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2026-10-20, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2026-11-03 ; treat that as the outer limit, not the target.
- EPSS 0.3% , percentile 17: FIRST’s model estimates a 0.3% chance of exploitation activity in the next 30 days, higher than 17% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
- Editorial verdict: Check exposure. Siemens Software Center DLL Flaw Abused in ClickFix Attacks — Siemens users get the fix automatically, but the real threat is attackers shipping their own signed, older copy as a malware loader, so Windows defenders should block the indicators and hunt rather than rely on patching.
