What the vulnerability does

01Description

The Shortcodes by United Themes plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 5.1.6. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

02Summary

Shortcodes by United Themes versions 5.1.6 and earlier contain a code injection vulnerability. An attacker can inject and execute arbitrary code through the plugin's shortcode processing without authentication. This allows reading sensitive data and modifying site content.
