CVE-2026-8382 Details
Description
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.
A vulnerability exists in the Advanced Custom Fields (ACF) plugin for WordPress, affecting all versions up to and including 6.8.1. The issue stems from the plugin's failure to properly verify user authorization, allowing unauthenticated attackers to overwrite the post title and content of any post linked to a publicly accessible ACF form. This is achieved by injecting values into the '_post_title' and '_post_content' parameters of the form submission request.
Users are advised to update the Advanced Custom Fields plugin to version 6.8.2 or later.
