Technical details
The GET /api/admin/users/{id}/calendar-heatmap endpoint uses only basic Permission.UserRead instead of admin-route enforcement, and UserAdminService does not verify that the authenticated user matches the requested user ID. An authenticated non-admin attacker can enumerate other users' upload/capture activity heatmaps across arbitrary date ranges. The returned data includes counts of archived and locked assets per day but not asset metadata or content, making this a confidentiality issue only.
