WordPress Core < 6.2.1 - Cross-Site Request Forgery

4.3
Cross-Site Request Forgery (CSRF)
CVSS 4.3 (Medium)
Publicly Published May 16, 2023

Researcher John Blackbourn - WordPress

Description

WordPress Core is vulnerable to Cross-Site Request Forgery due to missing nonce validation on the ‘wp_ajax_set_attachment_thumbnail’ AJAX function in versions up to, and including, 6.2. This allows unauthenticated users to update the thumbnail image associated with existing attachments, granted they can trick an authenticated user with appropriate permissions into performing an action, such as clicking a link. The impact of this vulnerability is incredibly minimal.
