Description

The GetGenie plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.3.2 due to missing validation on a user controlled key in the `action` function. This makes it possible for authenticated attackers, with Author-level access and above, to update post metadata for arbitrary posts. Combined with a lack of input sanitization, this leads to Stored Cross-Site Scripting when a higher-privileged user (such as an Administrator) views the affected post's "Competitor" tab in the GetGenie sidebar.
