Vulnerability Description

Joomla Extension - regularlabs.com - Authenticated, privileged remote code execution in Conditional Content extension for Joomla < 8.0.0 - Conditional Content Pro accepts inline PHP Condition Rules in article syntax. In affected versions, the PHP is passed to the Conditions evaluator without checking who authored the article. Joomla's normal Author text filter preserves the syntax, so publishing the article causes the code to run as the web-server process.
