Input validation vulnerability in WP Recipe Maker 9.2.1

The WP Recipe Maker add-on for WordPress has a security issue that could put websites at risk. This problem, called Stored Cross-Site Scripting, allows bad actors to add harmful code to pages on the website. This code can then be triggered and run whenever a user visits the infected page. This vulnerability affects all versions of the add-on up to version 9.2.1, and is caused by not properly checking and preventing malicious code from being added. This means that even if the user has administrator permissions, they could still be targeted by this attack.
