The Simple-File-List Plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 4.2.2 via the rename function which can be used to rename uploaded PHP code with a png extension to use a php extension. This allows unauthenticated attackers to execute code on the server.
An official patch is available. Apply the patch as soon as possible.
Consider disconnecting the vulnerable system from the internet until a fix is applied.
