Input validation vulnerability in Grand Conference | Event WordPress 5.2

  • Severity: critical
  • Status: Fixed
  • Publication: April 21, 2025

The Grand Conference plugin for WordPress has a security issue that allows hackers to inject a PHP Object. This can happen if they use untrusted information to deserialize the plugin. It is possible for someone to do this without having to log in. There is no known way for them to do this through the plugin itself. However, if the target system has other plugins or themes installed that have a POP chain, it could give the hacker access to delete files, gather private information, or run their own code on the website.
