CVE-2026-33906 Details
Description
Ella Core is a 5G core designed for private networks. Prior to version 1.7.0, the NetworkManager role was granted backup and restore permission. The restore endpoint accepted any valid SQLite file without verifying its contents. A NetworkManager could replace the production database with a tampered copy to escalate to Admin, gaining access to user management, audit logs, debug endpoints, and operator identity configuration that the role was explicitly denied. In version 1.7.0, backup and restore permissions have been removed from the NetworkManager role.
A privilege escalation vulnerability exists in Ella Core versions prior to 1.7.0, specifically within the NetworkManager role. The issue arises because the restore endpoint allowed any valid SQLite file to be uploaded without proper content verification. This lack of validation enabled a NetworkManager to replace the production database with a manipulated version, thereby escalating privileges to Admin. As a result, the individual could access user management features, audit logs, debug endpoints, and operator identity configurations that were normally restricted. In version 1.7.0, these backup and restore permissions were removed from the NetworkManager role.
Users can upgrade to Ella Core version 1.7.0 or later, where this vulnerability has been addressed.
