Details

Incus 6.0.5 before 6.0.7, 6.12.0 before 7.0.2, and 7.1.0 before 7.5.0 contains a restriction bypass vulnerability that allows restricted project users to use pull mode migration via clustered refresh requests. Attackers with instance creation rights can send a refresh migration request for an existing instance to make the server open outbound TLS websocket connections and probe reachable services.
