CVE-2016-11020

Name of the Vulnerable Software and Affected Versions: Kunena versions prior to 5.0.4

Description: The issue allows for XSS and potentially remote code execution due to the lack of restriction on avatar file extensions, which should be limited to gif, jpeg, jpg, and png.

Recommendations: For versions prior to 5.0.4, update to version 5.0.4 or later to resolve the issue. As a temporary workaround, consider restricting avatar file uploads to only gif, jpeg, jpg, and png extensions until a patch is applied.
