CVE-2026-44473: Ellanetworks Core

High severity, CVSS 7.1. EPSS: 0.3% chance of exploitation in the next 30 days.

Ella Core is a 5G core designed for private networks. Prior to 1.10.0, 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. This vulnerability is fixed in 1.10.0.

Affected products

• Ellanetworks Core: before 1.10.0 (fixed in 1.10.0)
