## Overview

Discourse is an open-source discussion platform. From versions 2026.1.0-latest to before 2026.1.3, 2026.2.0-latest to before 2026.2.2, and 2026.3.0-latest to before 2026.3.0, updating a category description via API is not sanitizing the description string, which can lead to XSS attacks. This issue has been patched in versions 2026.1.3, 2026.2.2, and 2026.3.0.

## Affected

- `discourse >= 2026.1.0, < 2026.1.3`
- `discourse >= 2026.2.0, < 2026.2.2`
- `discourse = 2026.3.0`

## Remediation
