What the vulnerability does
01Description
The WP Posts Re-order plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0. This is due to missing nonce validation on the `cpt_plugin_options()` function. This makes it possible for unauthenticated attackers to update the plugin settings including capability, autosort, and adminsort settings, via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
