CVE-2022-21874

Code execution through undisclosed API flaw

Published Jan 11, 2022 · Updated Jan 2, 2025

Remote code execution in the Windows Security Center API allows context-dependent attackers to execute code on affected Windows releases. Microsoft has not publicly disclosed the vulnerable API operation or how crafted input triggers code execution. Exploitation requires user interaction on the local system, after which attacker-controlled code runs with the affected process's privileges.
