GHSA-98F2-HWVC-W247

Vulnerability from github – Published: 2026-08-14 18:31 – Updated: 2026-09-15 00:31

Details

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.

Severity

8.1 (High)

Title

CVE-2026-16772

Summary

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.
