Authenticated users with contributor-level access or higher can exploit the flaw over the network without user interaction to place arbitrary files, including malicious executables, on the affected site. This capability directly enables full compromise of the WordPress installation and underlying server environment.
The vendor partially addressed the issue in version 1.5.66 and completed remediation in 1.5.67; Wordfence and WordPress plugin trac entries confirm the file-type checks were added to the unitecreator_assets.class.php component.
