The vulnerability lies in the WebSocket API used by Mobility46\u2019s system, which lacks a limit on the number of authentication requests a client may send. Without rate limiting this weakness allows an attacker to flood the service with authentication attempts, potentially overwhelming the application and causing denial of service, as well as to brute\u2011force credentials to gain unauthorized access.

The likely attack vector involves a remote attacker exploiting an open WebSocket endpoint from outside the network, repeatedly sending authentication messages to exhaust resources or guess credentials. The lack of commercial evidence of exploitation reduces the immediate risk, but the potential for a successful denial\u2011of\u2011service or unauthorized access event remains significant within affected environments."}}}}, "created": "2026-02-27T09:03:16.017052+00:00", "updated": "2026-04-16T06:00:10.186801+00:00", "vendors": ["mobility46", "mobility46$PRODUCT$mobility46.se"]}
