What is CVE-2025-12057?

The WavePlayer plugin for WordPress, prior to version 3.8.0, contains a critical vulnerability that allows unauthenticated users to exploit an AJAX action without proper authorization. By failing to validate the file intended for local copying, the vulnerability permits unauthorized file uploads to the server, which can potentially lead to remote code execution (RCE). This poses significant security risks for WordPress sites utilizing the plugin, as attackers can manipulate the server environment.
