Assigner: Wordfence

Description
The Custom Post Type UI plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.18.0. This is due to the plugin not verifying that a user has the required capability to perform actions in the "cptui_process_post_type" function. This makes it possible for authenticated attackers, with subscriber level access and above, to add, edit, or delete custom post types in limited situations.

Executive Summary

This vulnerability in the Custom Post Type UI plugin for WordPress allows authenticated users with subscriber level access or higher to bypass authorization checks. Specifically, the plugin does not verify if the user has the required capability when performing actions in the "cptui_process_post_type" function. As a result, these users can add, edit, or delete custom post types in certain situations, which they normally should not be able to do.

Impact Analysis

The vulnerability can impact you by allowing users with low-level access (subscriber or above) to modify custom post types without proper authorization. This could lead to unauthorized changes in your WordPress site's structure or content types, potentially disrupting site functionality, content integrity, or enabling further exploitation.

Mitigation Strategies

Update the Custom Post Type UI plugin to version 1.18.1 or later, which includes added capability checks to prevent unauthorized actions related to this vulnerability. [1]
