Vulnerability Overview

The Advanced Custom Fields (ACF) plugin for WordPress is vulnerable to arbitrary custom field access in all versions up to, and including, 6.2.10. This is due to the plugin not properly restricting what post meta can be displayed through the plugin's shortcode. This makes it possible for authenticated attackers, with Contributor-level access and above, to retrieve potentially sensitive information from custom fields.

Technical Analysis

REMEDIATION: Update to version 6.3.0, or a newer patched version --- IDENTIFIER: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
