## Overview

A flaw was found in GI-DocGen. This vulnerability allows arbitrary JavaScript execution in the context of the page — enabling DOM access, session cookie theft and other client-side attacks — via a crafted URL that supplies a malicious value to the q GET parameter (reflected DOM XSS).

## Affected packages

- `gi-docgen < 2025.5`

## Remediation

Upgrade to a patched release:

- `gi-docgen 2025.5`
