Executive brief
Fabrik is a Joomla application builder component that allows users to create custom forms and lists for collecting and displaying data. An unauthenticated attacker can retrieve the email addresses of any commenter by exploiting a missing access control check in the onGetEmail endpoint, potentially exposing user contact information and enabling targeted attacks.
Technical details
The vulnerability is an access control bypass (CWE-284) in the onGetEmail endpoint of the Fabrik Joomla component. The endpoint fails to perform any authentication or authorization checks before returning commenter email addresses. An unauthenticated attacker on the network can directly call this endpoint to enumerate and retrieve email addresses of all commenters without requiring credentials or user interaction. The vulnerability affects Fabrik versions before 4.7.2 and has been remediated in version 4.7.2 and later.
