Description

The WP Security Question plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.5. This is due to missing or incorrect nonce validation on the save() function. This makes it possible for unauthenticated attackers to modify the plugin's settings 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

  • flippercode WP Security Question — Up to and including 1.0.5
  • flippercode wp-security-questions — Up to and including 1.0.5
