## Overview

Coder before 2.29.17, 2.30.0 before 2.32.7, 2.33.0 before 2.33.8, and 2.34.0 before 2.34.2 contains a stored HTML injection vulnerability because the ApplicationName and LogoURL appearance settings are rendered into HTML output without sufficient escaping. Attackers with the Owner role can store HTML markup in these settings that renders in the Coder dashboard and in SMTP notification emails sent to other deployment users.

## Affected

- `coder >= 2.34.0 < 2.34.2`
- `coder >= 2.33.0 < 2.33.8`
- `coder >= 2.30.0 < 2.32.7`
- `coder < 2.29.17`
