Exploitation Summary

CVE-2025-13486 has been observed exploited in the wild (reported by VulnCheck KEV). EIP tracks 9 public exploits from researchers including 0xanis, 0xgh057r3c0n, MataKucing-OFC, including a Metasploit module exploits/multi/http/wp_acf_extended_rce. A Nuclei detection template is also available.

AI-analyzed exploit summary This PoC exploits CVE-2025-13486, an RCE vulnerability in the Advanced Custom Fields: Extended WordPress plugin, by leveraging improper validation in the `acfe/form/render_form_ajax` AJAX action to execute arbitrary PHP functions. It includes both verification and exploitation modes, with the latter creating an administrator account.

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.
