GitHub Security Advisory

Potential XSS vulnerability in jQuery

✓ GitHub Reviewed MODERATE Has CVE

Advisory Details

### Impact
Passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. `.html()`, `.append()`, and others) may execute untrusted code.

### Patches
This problem is patched in jQuery 3.5.0.

### Workarounds
To workaround the issue without upgrading, adding the following to your code:

```js
jQuery.htmlPrefilter = function( html ) {
return html;
};
```

You need to use at least jQuery 1.12/2.2 or newer to be able to apply this workaround.
