Name of the Vulnerable Software and Affected Versions Vanilla Forums versions prior to 2.0.17

Description A cross-site scripting (XSS) issue allows remote attackers to inject arbitrary web script or HTML via the Target parameter in a "/entry/signin" action. This could potentially lead to unauthorized actions on behalf of the user.

Recommendations For versions prior to 2.0.17, update to version 2.0.17 or later to resolve the issue. As a temporary workaround, consider restricting access to the "/entry/signin" action to minimize the risk of exploitation. Avoid using the Target parameter in the affected API endpoint until the issue is resolved.
