Answer in brief
CVE-2026-24349 records a High severity (CVSS 7.1) vulnerability in CISA ADP Vulnrichment. The current sources do not mark it as known exploited. The current feed maps Siemens/SIMATIC WinCC Unified PC Runtime V16 (generic), Siemens/SIMATIC WinCC Unified PC Runtime V17 (generic), Siemens/SIMATIC WinCC Unified PC Runtime V18 (generic), Siemens/SIMATIC WinCC Unified PC Runtime V19 (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.
