Input validation vulnerability in PressGrid – Frontend Publish Reaction & Multimedia Theme 1.3.1

The PressGrid theme for WordPress has a security vulnerability that allows attackers to inject a harmful code into the website. This can only happen if the attacker has access to the website, and if there is another plugin or theme that also has a security issue. If this is the case, the attacker may be able to delete files, access confidential information, or run unauthorized code.
