## Overview

DOMPurify 3.1.3 through 3.2.6 and 2.5.3 through 2.5.8 contain a cross-site scripting vulnerability that allows attackers to bypass attribute sanitization by exploiting missing textarea rawtext element validation in the SAFE_FOR_XML regex. Attackers can include closing rawtext tags like </textarea> in attribute values to break out of rawtext contexts and execute JavaScript when sanitized output is placed inside rawtext elements. The 3.x branch was fixed in 3.2.7; the 2.x branch was never patched.

## Affected

- `dompurify >= 2.5.3, <= 2.5.8`
- `dompurify >= 3.1.3, < 3.2.7`

## Remediation

Upgrade past the affected range:

- `dompurify 3.2.7`
