## Summary A radio with a valid NG Setup can send a forged PDUSessionResourceSetupResponse carrying any UE's AMF-UE-NGAP-ID. Ella Core does not verify the message arrived on the SCTP association bound to that UE's logical NG-connection, then creates a GTP tunnel towards that radio. ## Impact Downlink user-plane traffic for the targeted UE is redirected to the attacker's radio. ## Fix UE context lookups are now scoped to the sending radio's SCTP association.
Update github.com/ellanetworks/core to 1.10.0 if you use the affected versions. Test the change in a non-production environment first.

AI coding agents often install or upgrade packages automatically in go. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
