CVE-2022-51019

Akaunting 3.1.21 contains an authenticated improper authorization vulnerability in the common BulkActions dispatcher.

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.

In Akaunting, the shared download route (uploads/{id}/download) does not verify that the requested file belongs to the logged-in customer's company. An authenticated portal customer can download other companies' uploaded files by guessing or enumerating media IDs.
