Description

The Rucy plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 0.4.4. This is due to missing or incorrect nonce validation on the save_rc_post_meta() function. This makes it possible for unauthenticated attackers to save post meta via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • gips-nita Rucy — Up to and including 0.4.4
  • rucy_project rucy — Up to and including 0.4.4
