CVE-2026-34762 Details
Description
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.
A vulnerability exists in Ella Core versions prior to 1.8.0, specifically in the PUT /api/v1/subscriber/{imsi} API. This API accepts an IMSI identifier from both the URL path and the JSON request body but fails to verify that they match. As a result, an authenticated NetworkManager can alter any subscriber's policy while the audit trail records a fabricated or unrelated subscriber IMSI. This discrepancy can hinder post-incident forensic searches for the affected subscriber's IMSI, as no matching audit entries would be found.
Users can upgrade to Ella Core version 1.8.0, where this vulnerability has been patched.
