Executive Summary

This vulnerability affects the Joomla extension Fabrik (versions below 4.7.2). It allows unauthenticated users to delete any comment via the DeleteComment endpoint without performing access checks.

Detection Guidance

To detect this vulnerability, check if Fabrik for Joomla versions below 4.7.2 are installed. Inspect web server logs for unusual DELETE requests to the /index.php?option=com_fabrik&task=plugin.pluginAjax&plugin=fabrik_comment&method=deleteComment endpoint. Look for requests without authentication.

Impact Analysis

An attacker could exploit this to delete comments without permission, potentially causing data loss or disrupting functionality. The impact is limited to comment deletion as no other actions are affected.

Compliance Impact

This vulnerability could impact compliance if comments contain regulated data (e.g., personal or health information). Unauthorized deletion may violate integrity requirements in GDPR or HIPAA.

Mitigation Strategies

Immediately update Fabrik for Joomla to version 4.7.2 or later. If updating is not possible, disable the Fabrik component or restrict access to the vulnerable endpoint via web server rules until a patch is applied.
