## Summary Ella Core does not verify the UE Security Capabilities received in NGAP PathSwitchRequest messages against its locally stored values. A malicious gNB can overwrite Ella Core's stored UE security capabilities for any UE with arbitrary values by sending a single crafted PathSwitchRequest. ## Impact A gNB can corrupt Ella Core's stored UE security capabilities for a target UE. ## Fix The PathSwitchRequest handler now compares the received UE Security Capabilities against Ella Core's locally stored values, preserves the stored values on mismatch, returns them in the PathSwitchRequestAcknowledge, and logs the event.
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 medium 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.
