Vulnerability Description

In Akaunting versions <= 3.1.21, low‑privileged authenticated users can modify their own account to assign themselves the admin role ID, granting full administrator privileges. This vulnerability is caused by a flaw in the `UpdateUser` job, which processes user-supplied role assignments via an unconditional `roles()->sync()` call without verifying whether the caller is authorized to manage roles. Users only require the default `update-auth-profile` permission to access the self-update path and assign themselves as admins. The API endpoints are properly permission‑gated and are not affected by this issue. This vulnerability has been remediated in v3.2.0, commit 80ef6d3b154a.
