CVE-2026-56241 · Severity: high · CVSS 8.3 · Published 2026-07-12

Capgo, a platform for managing over-the-air (OTA) updates, contains a flaw where users who were previously administrators retain high-level permissions even after being demoted. This allows a demoted user to continue viewing and deleting critical application bundles across an entire organization. Exploitation could lead to service disruptions, as affected devices would stop receiving necessary software updates.

## Technical details

A privilege escalation vulnerability exists in Capgo versions prior to 12.128.2 due to improper authorization checks in the Role-Based Access Control (RBAC) system. When a user's 'super_admin' role binding is deleted via the API, the system fails to clear the legacy 'org_users.user_right' column in the database. Furthermore, the 'delete_non_compliant_bundles' and 'count_non_compliant_bundles' RPCs rely on this legacy column for authorization instead of the modern RBAC permission checks. An authenticated attacker with a previously held administrative role can exploit this to enumerate and bulk-delete non-compliant bundles across an organization indefinitely. The issue is resolved in version 12.128.2 by migrating the RPCs to use 'rbac_check_permission_direct()' and ensuring the demotion process correctly updates legacy columns.
