Remote code execution via crafted malicious file
Published Jul 11, 2023 · Updated Aug 10, 2026
Windows Search in affected Microsoft Windows builds allows remote attackers to execute code through a crafted malicious file opened by a user. Microsoft has not published the precise race condition or the Windows Search operation that mishandles the file, but CISA states that the file evades Mark of the Web defenses. Exploitation requires user interaction with the file and can run attacker-controlled code in the user's security context.
