CVE-2026-88860 Details
Description
Capgo fails to clean up channel permission overrides when a user's last organization role binding is deleted, leaving stale overrides active. Attackers can retain channel-specific permissions after their base RBAC access has been revoked to perform unauthorized actions like changing production OTA versions.
A vulnerability exists in Capgo that allows users to retain channel-specific permissions after their last organization role binding has been deleted. This issue arises because the application fails to remove channel permission overrides when a user's organizational role is revoked, leaving outdated permissions active. As a result, users can perform unauthorized actions, such as changing production over-the-air (OTA) versions, even after their base role-based access control (RBAC) rights have been removed.
This vulnerability has been addressed in Capgo version 12.258.0. Users should update to this version to mitigate the issue.
