Akaunting 3.3.0 - Stored XSS in invoice edit form through imported status

Published Nov 12, 2026 CVSS 4.0 · 7 High EPSS < 1% KEV · Not listed
Description
Akaunting 3.3.0 contains a stored cross-site scripting vulnerability through invoice import. An authenticated user with invoice-creation permission can import HTML in an invoice status field. When another authenticated user opens that invoice's edit form, Akaunting renders the stored status in a hidden input with raw Blade output, allowing attacker-controlled markup to execute in the victim's Akaunting origin.

Remediation

Vendor Solution

Restore a strict allowlist for invoice statuses during normal and spreadsheet-import validation, and change the hidden-input component to encode its value in attribute context. Upgrade to the vendor-fixed release once one is published.


Vendor Workaround

Restrict invoice-import permission to trusted users and do not open edit pages for invoices imported from untrusted sources. Remove document rows whose status is not a supported state identifier. These measures are temporary and do not replace output encoding.
