Users should upgrade the plugin once a fixed version is released. Until then, consider disabling or restricting file upload functionality in the plugin or limiting access to trusted users only. Monitoring for updates from the plugin vendor or WordPress security advisories is recommended.
Description
The Advance Guest Post WordPress plugin up to version 1.9 contains an unrestricted file upload vulnerability that allows unauthenticated users to upload arbitrary PHP files and execute code remotely. This occurs because the plugin improperly restricts file uploads, authorizing the upload action with a nonce exposed to all front-end visitors and validating only the file's leading bytes. Exploitation requires the target to be running PHP 7.x, as PHP 8.0 and later cause a fatal error before the file is written.
