CISA warned US organizations Thursday about a critical vulnerability (CVE-2026-4681) in PTC's Windchill software that allows remote attackers to execute code without authentication. The flaw affects the company's product lifecycle management tools used by industrial organizations. The vulnerability sparked unprecedented action in Germany, where police were deployed across multiple states to physically visit companies and warn them about the risk. Officers reportedly showed up at some businesses in the middle of the night to deliver urgent security alerts. PTC hasn't released patches yet but provided temporary mitigations and indicators to detect attacks. While there's no evidence of active exploitation, the dramatic German response suggests threat actors may soon target this vulnerability. **Source:** [Security Week](https://www.securityweek.com/cisa-flags-critical-ptc-vulnerability-that-had-german-police-mobilized/)
