CVE-2026-16772
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk10th percentile - higher than 10% of all known CVEs
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.
Risk Assessment
The risk for the organization is privilege escalation by low-privileged authenticated users, potentially leading to full compromise of the Akaunting system.
Recommendation
It is recommended to immediately upgrade Akaunting to a version newer than 3.1.21 that includes the fix. Also, restrict user permissions and monitor account activity.
