## Affected

- wpblast WP Blast | SEO & Performance Booster: through 1.8.6

## Description

The WP Blast | SEO & Performance Booster plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.8.6. This is due to missing or incorrect nonce validation on multiple administrative actions in the Settings class. This makes it possible for unauthenticated attackers to trigger cache purging, sitemap clearing, plugin data purging, and score resetting operations via forged requests granted they can trick a site administrator into performing an action such as clicking on a link.
