Copilot Web
Monthly
Command injection in Microsoft Copilot Web (copilot_web) enables unauthenticated remote attackers to exfiltrate sensitive data over the network by embedding malicious command elements in user-controlled input. The impact is strictly bounded to confidentiality - no integrity or availability loss - and a proof-of-concept is publicly available on GitHub. Despite a CVSS 7.5 score and public PoC, SSVC classifies exploitation as none with Automatable=no, and EPSS sits at 1.63%, suggesting limited real-world exploitation activity at time of analysis.
