Description

The Laiser Tag plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.2.5. This is due to missing or incorrect nonce validation on the addOptionsPageFields function. This makes it possible for unauthenticated attackers to update the plugin's settings, including the API key, tag blacklist, relevance threshold, batch size, and tagging toggles, via a forged request via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
