Arcane: Delegated users:update permission allows admin account takeover via password reset (no privilege-hierarchy check)

Published Oct 16, 2026 CVSS 3.1 · 8.8 High EPSS < 1% KEV · Not listed
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.
