CVE-2026-2257
CWE-639Published: March 13, 2026· Updated: Mar 16, 2026
Official 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.
Technical Analysis
CVE-2026-2257 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
