Until a fix is available, restrict file upload permissions and consider disabling the plugin or limiting access to trusted users only.

Description

The Advance Guest Post WordPress plugin versions through 1.9 improperly validate uploaded files by using a case-sensitive and incomplete extension check. This flaw allows unauthenticated users to bypass validation and upload arbitrary files, including executable PHP variants, to a web-accessible directory. Depending on the server configuration, this can lead to remote code execution.
