Technical details
The StageIt Joomla extension contains CSRF vulnerabilities across multiple actions in versions 1.0-5.7.5 and 6.0-6.3.5. CSRF occurs when the extension does not properly validate request tokens, allowing attackers to craft malicious requests that execute when an administrator visits a compromised page. No network access or user interaction beyond visiting a malicious page is required beyond the target being logged into the admin panel.
