Details

FlexRIC v2.0.0 contains an authorization bypass in the iApp's xApp isolation mechanism. The equality function eqxappricgenid() in src/ric/iApp/xappricid.c compares m0->xappid against itself (m0->xappid) instead of the other argument (m1->xappid), 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 E42RICSUBSCRIPTIONDELETEREQUEST with a matching ricgen_id. This breaks multi-tenant isolation in any deployment with multiple xApps sharing the same RIC.
