Description

The WP-Backgrounds Lite plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.3. This is due to missing or incorrect nonce validation on the ino_save_data() function. This makes it possible for unauthenticated attackers to save meta data 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

  • inoplugs WP-Backgrounds Lite — Up to and including 2.3
  • inoplugs wp-backgrounds-lite — Up to and including 2.3
