Akaunting 3.3.0 - Stored XSS through imported invoice numbers

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 in the XLSX invoice-import workflow. An authenticated Manager can import a child invoice whose invoice number contains HTML and is linked to a recurring invoice. When a victim opens that recurring invoice, Akaunting raw-renders the stored child number in an anchor, causing attacker-controlled markup to execute in the victim's browser.

Remediation

Vendor Solution

Escape document_number in the recurring-child view, remove the raw translation sink, normalize or reject markup in invoice-number imports, and add import-to-recurring-child rendering regression tests.


Vendor Workaround

Restrict invoice imports to trusted administrators, inspect existing document numbers for markup, and avoid opening recurring invoices with children imported from untrusted workbooks.
