# CHANGELOG
## 6.0.4
- Add additional null byte sanitization prior to html decoding (#48)
## 6.0.3
- Add null check to beginning of `sanitizeUrl` function ([#54](https://github.com/braintree/sanitize-url/issues/54))
## 6.0.2
- Fix issue where urls in the form `https://example.com

/something` were not properly sanitized

## 6.0.0
**Breaking Changes**
- Decode HTML characters automatically that would result in an XSS vulnerability when rendering links via a server rendered HTML file
```js
// decodes to javacript:alert('XSS')
const vulnerableUrl =
"javascript:alert('XSS')";
sanitizeUrl(vulnerableUrl); // 'about:blank'
const okUrl = "https://example.com/" + vulnerableUrl;
// since the javascript bit is in the path instead of the protocol
// this is successfully sanitized
sanitizeUrl(okUrl); // 'https://example.com/javascript:alert('XSS');
```
