Versions of `dompurify` prior to 2.0.3 are vulnerable to Cross-Site Scripting (XSS). The package has an XSS filter bypass due to Mutation XSS in both Chrome and Safari through a combination of `<svg>`/`<math>` elements and `</p>`/`</br>`. An example payload is: `<svg></p><style><a id="</style><img src=1 onerror=alert(1)>">`. This allows attackers to bypass the XSS protection and execute arbitrary JavaScript in a victim's browser.

## Recommendation

Upgrade to version 2.0.3 or later. You may also disallow `<svg>` and `<math>` through `dompurify` configurations: ```DOMPurify.sanitize(input, { FORBID_TAGS: ['svg', 'math'] });```
