- CVE-2026-44473High
Ella Core, designed for private 5G networks, prior to version 1.10.0, allowed a radio with a valid NG Setup to send forged PDUSessionResourceSetupResponse messages. The system did not verify if the message arrived over the correct NG connection, leading to the creation of a GTP tunnel towards that radio.
- CVE-2026-34762Low
In Ella Core prior to version 1.8.0, the PUT /api/v1/subscriber/{imsi} API does not verify that the IMSI from the URL path matches the IMSI from the JSON request body. An authenticated NetworkManager can modify any subscriber's policy while the audit trail records a fabricated IMSI. This is fixed in version 1.8.0.
- CVE-2026-34761Medium
Ella Core, a 5G core for private networks, prior to version 1.8.0 panics when processing a NGAP handover failure message. An attacker can send such messages via gNodeB, causing service disruption for all connected subscribers.
