AI-analyzed exploit summary This is a functional exploit for CVE-2025-3776, targeting a Remote Code Execution (RCE) vulnerability in the 'Verification SMS with TargetSMS' WordPress plugin <= 1.5. The exploit leverages an unsafe use of `call_user_func()` on user-controlled input, allowing unauthenticated attackers to execute arbitrary commands if a malicious function is pre-loaded into memory.

Description

The Verification SMS with TargetSMS plugin for WordPress is vulnerable to limited Remote Code Execution in all versions up to, and including, 1.5 via the 'targetvr_ajax_handler' function. This is due to a lack of validation on the type of function that can be called. This makes it possible for unauthenticated attackers to execute any callable function on the site, such as phpinfo().
