Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Arcane (Go module github.com/getarcaneapp/arcane/backend/v2) versions before 2.6.0 are affected. A user holding the delegated users:update permission can set the password of any account, including the global administrator's, because the update path performs no check comparing the caller's privileges with the target's. An attacker with that permission could then log in as the administrator and take over the admin account. Upgrade to version 2.6.0 or later.
