CVE-2026-96627
Arcane: Delegated users:update permission allows admin account takeover via password reset (no privilege-hierarchy check)
Description
Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to 2.6.0, UpdateUser in backend/api/handlers/users.go sets PasswordHash for any target without comparing caller and target privilege. A holder of delegated users:update permission can submit a password change for the global administrator, replace the administrator password, and authenticate as that account, resulting in complete global administrator account takeover. This issue is fixed in version 2.6.0.
