CVE-2023-2941Network attack vector

UI spoofing via crafted malicious extension

Published May 30, 2023 · Updated Mar 11, 2025

UI spoofing in the Extensions API in Google Chrome before 114.0.5735.90 allows attackers to misrepresent browser interface content. Google identifies an inappropriate Extensions API implementation but has not published the faulty operation because the underlying bug remains restricted. Exploitation requires a user to install a crafted malicious extension; the reported consequence is UI-content spoofing, not code execution or data disclosure.
