| 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. |

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