Description
The Urvanov Syntax Highlighter plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.8.33. This is due to missing or incorrect nonce validation on the init_ajax function. This makes it possible for unauthenticated attackers to perform multiple actions including saving, submitting, duplicating, and deleting syntax highlighting blocks via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
