Description
Vanus 0.8.0 through 0.9.0 contains a missing authorization vulnerability in the gateway that allows any authenticated user to call Subscribe, Ack, and unregistered methods without permission checks. Attackers can supply another tenant's subscription ID to Subscribe to hijack it, read and acknowledge its events, starve the legitimate consumer, and enumerate cluster users via ListUser.
