CVE-2026-96627 · Arcane: Delegated users:update permission allows admin account takeover via password reset (no privilege-hierarchy check)

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
