**Name of the Vulnerable Software and Affected Versions** Joomla! AkoBook component version 2.3 **Description** The issue allows remote attackers to execute arbitrary SQL commands. This is achieved via the `gbid` parameter in a reply action to "index.php". **Recommendations** For version 2.3, consider restricting access to the reply action in index.php to minimize the risk of exploitation. Avoid using the `gbid` parameter in the affected API endpoint until the issue is resolved.
