# Akaunting: stored XSS via XLSX invoice import runs script in browsers

Link for people: https://infrastack.ai/live/CVE-2026-119275 (this .md is for agents)

Akaunting 3.3.0 renders imported invoice numbers unescaped on the recurring-invoice page. A Manager who imports an invoice with HTML in its number, linked to a recurring invoice, runs script in the browser of any user who opens that page. A public proof of concept exists; no fixed version is published yet.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- packagist:akaunting/akaunting affected = 3.3.0 fixed no fixed version listed

## How to check

Run Akaunting 3.3.0? Check the version shown in the admin footer. Then look for HTML in invoice numbers: SELECT id, document_number, parent_id FROM documents WHERE document_number LIKE '%<%'; Also check if you run a nearby version, since the advisory only tested 3.3.0.

- 2026-11-12T18:43:32+00:00 analyst https://fluidattacks.com/advisories/soda — Read Fluid Attacks CNA advisory (researcher's, not Akaunting's). Only 3.3.0 confirmed affected; no fixed version stated, vendor contacted Oct 29, no vendor reply seen, so fix left unknown. Public PoC in advisory. Nothing verified: no vendor/maintainer page.

## Documents

- [advisory] Akaunting 3.3.0 - Stored XSS through imported invoice numbers (Fluid Attacks) https://fluidattacks.com/advisories/soda

## From the sources

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.
