Name of the Vulnerable Software and Affected Versions Knowage Suite versions prior to 7.4

Description The issue allows an attacker to inject arbitrary web script in "/restful-services/publish" via the EXEC FROM parameter, which can lead to data leakage. This is a case of reflected cross-site scripting (XSS).

Recommendations For versions prior to 7.4, update to version 7.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the "/restful-services/publish" endpoint to minimize the risk of exploitation. Avoid using the EXEC FROM parameter in the affected API endpoint until the issue is resolved.
