# Akaunting: stored XSS in invoice payment terms runs script for other users

Link for people: https://infrastack.ai/live/CVE-2026-118597 (this .md is for agents)

Akaunting 3.3.0 lets a logged-in Manager save a crafted custom invoice payment-term value. When another authorized user opens Invoice Settings for the same company, the stored value runs as JavaScript in their logged-in session.

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

## Affected

- vendor:Akaunting affected 3.3.0 fixed no fixed version listed

## How to check

- Check whether the installed Akaunting version is 3.3.0 (Settings/About or composer/version file).
- Review custom payment terms in Invoice Settings for script-like text (quotes, <, onclick/event-handler fragments).
- Check which users hold the Manager role; the flaw needs a Manager to plant the value.
- Also check 3.3.1: its release notes do not list an XSS fix, so do not assume it is patched.

## Timeline

- 2026-11-12T06:36:51+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-118597
- 2026-11-12T06:38:42+00:00 analyst https://github.com/akaunting/akaunting/releases — No primary advisory found (NVD page not retrievable; Fluid Attacks CNA entry only via NVD). Akaunting 3.3.1 release notes (11 Nov) do not mention this XSS, so fix is unconfirmed. Nothing verified.

## Documents

- [mentions] Akaunting releases (3.3.0, 3.3.1) https://github.com/akaunting/akaunting/releases

## From the sources

Akaunting 3.3.0 contains a stored cross-site scripting vulnerability in custom invoice payment terms. An authenticated Manager can save a crafted custom payment-term value. When an authorized user opens Invoice Settings for the same company, Akaunting inserts the stored value into a client-side event-handler expression, causing attacker-controlled JavaScript to execute in the victim's authenticated origin.
