Description
The Kirki WordPress plugin before 6.2.3 does not properly validate the files contained in archives uploaded by users with the Editor role, and does not remove all unwanted files after extracting them, allowing such users to upload arbitrary files to a web accessible directory, leading to Stored XSS as well as RCE on some server configurations.
