Description
The LH Signing plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.83. This is due to missing or incorrect nonce validation on the plugin_options function. This makes it possible for unauthenticated attackers to modify plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
