Summary

AiSOC versions 7.5.0 before 12.0.0 use a hard-coded constant for JWT verification in the realtime WebSocket and SSE service when the AISOC_REALTIME_JWT_SECRET environment variable is not set. Unauthenticated attackers can forge subscription tickets with arbitrary tenant identifiers to access cross-tenant live alerts, cases, agent events and graph updates through the realtime endpoints.
