Auth bypass in Mgdaaslab Wharttest
CVE-2026-111617
WHartTest through 2.8.1 contains a missing authentication vulnerability that allows unauthenticated attackers to connect to the /ws/ui/web/ and /ws/ui/actuator/ WebSocket endpoints because UiAutomationConsumer accepts every connection. Attackers can register an actuator with a client-supplied id to intercept other users' test-case payloads, receive broadcast step results, and spoof results and screen frames into victim sessions.
