**Name of the Vulnerable Software and Affected Versions** WSO2 API Manager versions prior to 4.2.0 **Description** A reflected cross-site scripting (XSS) issue allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the `tenantDomain` parameter in the "/authenticationendpoint/login.do" API endpoint. **Recommendations** For versions prior to 4.2.0, update to version 4.2.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the "/authenticationendpoint/login.do" API endpoint to minimize the risk of exploitation. Avoid using the `tenantDomain` parameter in the affected API endpoint until the issue is resolved.
