Input validation vulnerability in Remove Schema 1.5

The Remove Schema WordPress plugin is vulnerable to a type of attack called Cross-Site Request Forgery. This type of attack can happen if the plugin is installed on a WordPress website and is using version 1.5 or earlier. This vulnerability occurs because the plugin doesn’t have enough security measures in place, specifically something called a “nonce validation” on a function called “validate”. This means that a malicious user could potentially trick a website administrator into clicking a link, and by doing this, they can modify the plugin settings without authorization.
