Executive brief
4Analytics is a Joomla extension used for private website traffic analysis and AI-driven reporting. A security vulnerability allows unauthenticated attackers to inject malicious scripts into the AI analysis feature. If an administrator views these reports, the scripts could execute, potentially leading to unauthorized access to the website management console or theft of sensitive administrative data.
Technical details
The 4Analytics extension for Joomla (versions 1.0 through 5.0.1) contains a stored Cross-Site Scripting (XSS) vulnerability (CWE-79). The flaw exists in the AI analysis component, where input is improperly neutralized before being rendered in the Joomla administrative interface or emailed reports. An unauthenticated remote attacker can exploit this by submitting malicious data that the AI processes, which then executes in the context of a logged-in administrator's session. This can lead to full administrative compromise. The vulnerability is addressed in versions following 5.0.1.
