Name of the Vulnerable Software and Affected Versions TheGem theme for WordPress versions up to and including 5.10.3

Description The issue concerns unauthorized modification of data due to a missing capability check in the ajaxApi() function. This allows authenticated attackers with Subscriber-level access or higher to update arbitrary theme options.
