Technical details

The Advanced Custom Fields: Extended (ACFE) plugin for WordPress is vulnerable to arbitrary shortcode execution due to a lack of input validation in the form rendering and email action modules. Specifically, the software allows unauthenticated users to trigger actions that pass unvalidated values into the WordPress 'do_shortcode' function. An attacker can exploit this by submitting crafted requests to the front-end form rendering components or email action handlers. This can lead to the execution of any registered shortcode on the site, potentially resulting in information disclosure or further exploitation depending on the available shortcodes. The vulnerability is present in versions up to and including 0.9.2.3.
