Improper neutralization of special elements used in a command ('command injection') in Windows Clipboard User Service allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in the Windows Clipboard User Service lets an already-authenticated low-privileged user run OS commands in the service's higher-privilege security context by injecting special elements into a command the service constructs (CWE-77). Affected platforms are Windows 11 24H2/25H2 and Windows Server 2025 (including Server Core). Microsoft has issued a patch; there is no public exploit identified at time of analysis and the flaw is not on the CISA KEV list.
