Name of the Vulnerable Software and Affected Versions Display custom fields in the frontend – Post and User Profile Fields plugin for WordPress versions up to, and including, 1.2.1

Description The issue allows authenticated attackers with contributor-level access and above to retrieve potentially sensitive post meta due to missing validation on a user-controlled key in the vg display data shortcode. This enables them to access data they should not have access to.

Recommendations For versions up to, and including, 1.2.1, update to a version that includes the necessary validation for the vg display data shortcode to prevent unauthorized access to post meta. As a temporary workaround, consider restricting access to the vg display data shortcode for users with contributor-level access and above until a patch is available.
