AI-suggested

Until a fix is available, consider disabling or removing the Advance Guest Post plugin or upgrading PHP to version 8.0 or later to prevent exploitation.

Description

The Advance Guest Post WordPress plugin up to version 1.9 contains a vulnerability that allows unauthenticated users to upload arbitrary PHP files due to improper file upload validation and a nonce exposed to all front-end visitors. This enables remote code execution on sites running PHP 7.x. The vulnerability does not affect PHP 8.0 and later, where the vulnerable code path triggers a fatal error before file upload completion.
