FlexRIC v2.0.0 contains an authorization bypass in the iApp's xApp isolation mechanism. The equality function eq_xapp_ric_gen_id() in src/ric/iApp/xapp_ric_id.c compares m0->xapp_id against itself (m0->xapp_id) instead of the other argument (m1->xapp_id), effectively ignoring the xApp identity dimension. A malicious xApp connected to the iApp (port 36422) can delete any other xApp's subscriptions by sending an E42_RIC_SUBSCRIPTION_DELETE_REQUEST with a matching ric_gen_id. This breaks multi-tenant isolation in any deployment with multiple xApps sharing the same RIC.
