Home page URL: Security reports for Advanced Custom Fields: Extended
Application: Advanced Custom Fields: Extended
Published on: Dec 03, 2025
Research Description: The Advanced Custom Fields: Extended plugin for WordPress is vulnerable to Remote Code Execution in versions 0.9.0.5 through 0.9.1.1 via the prepare_form() function. This is due to the function accepting user input and then passing that through call_user_func_array(). This makes it possible for unauthenticated attackers to execute arbitrary code on the server, which can be leveraged to inject backdoors or create new administrative user accounts.
Affected versions: max 0.9.2.
Status: vulnerable
