Output validation vulnerability in UNIVERSAM 8.72.34

The UNIVERSAM plugin for WordPress, which is used to add features to a website, has a security issue in versions 8.72.34 and below. This can be exploited by hackers to insert malicious code without needing to be logged in. While there is no known way for them to do this currently, if there is another plugin or theme installed that does allow it, they could potentially delete important files, access private information, or run their own code on the website.
