Until a fix is available, users should exercise caution when opening files from untrusted sources and follow Siemens' security recommendations.

Description

CVE-2026-59082 is a high-severity vulnerability in Siemens SIMATIC WinCC versions 7.5, 8.0, and 8.1. The affected software implicitly executes active content when opening files, which can lead to arbitrary code execution by an attacker if the user is tricked into opening a malicious file. This is due to insufficient user interface warnings about dangerous operations.
