CVE-2026-34762: Ellanetworks Ella Core

Low severity, CVSS 2.7. EPSS: 0.3% chance of exploitation in the next 30 days.

Ella Core is a 5G core designed for private networks. Prior to version 1.8.0, the PUT /api/v1/subscriber/{imsi} API accepts an IMSI identifier from both the URL path and the JSON request body but never verifies they match. This allows an authenticated NetworkManager to modify any subscriber's policy while the audit trail records a fabricated or unrelated subscriber IMSI. This issue has been patched in version 1.8.0.

Affected products

• Ellanetworks Ella Core: before 1.8.0 (fixed in 1.8.0)
