The Advanced Custom Fields (ACF) plugin for WordPress is vulnerable to Missing Authorization to Arbitrary Post/Page Disclosure in versions up to and including 6.7.0. This is due to AJAX field query endpoints accepting user-supplied filter parameters that override field-configured restrictions without proper authorization checks. This makes it possible for unauthenticated attackers with access to a frontend ACF form to enumerate and disclose information about draft/private posts, restricted post types, and other data that should be restricted by field configuration.5.3CVE-2026-8382wordpressadvanced-custom-fields+1

The Advanced Custom Fields (ACF®) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.8.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to overwrite the post_title and post_content of any post bound to a publicly accessible acf_form() instance by injecting values into the _post_title and _post_content parameters of a form submission request.6.4CVE-2023-6701advancedcustomfieldsadvanced_custom_fields+4
