Overview
A critical Remote Code Execution (RCE) vulnerability, identified as CVE-2025-6389, has been discovered in the Sneeit Framework plugin for WordPress. This vulnerability affects all versions up to, and including, 8.3. Exploitation of this flaw allows unauthenticated attackers to execute arbitrary code on the server hosting the WordPress site. This poses a significant threat to website security and data integrity.
Technical Details
The vulnerability resides within the sneeit_articles_pagination_callback() function. This function improperly handles user-supplied input, directly passing it to the call_user_func() function. call_user_func() is a PHP function that calls a function specified by a string. By crafting malicious input, an attacker can force call_user_func() to execute arbitrary PHP code. This bypasses security measures and allows for full control over the server.
