Summary
smartbanner.js rel noopener vulnerability
Details

rel noopener vulnerability

Impact

Clicking on smartbanner View link and navigating to 3rd party page leaves window.opener exposed. It may allow hostile 3rd parties to abuse window.opener, e.g. by redirection or injection on the original page with smartbanner.

Patches

rel="noopener" is automatically populated to links as of v1.14.1 which is a recommended upgrade to resolve the vulnerability.

Workarounds

If you can not upgrade to v1.14.1: 1. Ensure View link is only taking users to App Store or Google Play Store where security is guarded by respective app store security teams 2. If View link is going to a 3rd party page, limit smartbanner.js to be used on iOS that decreases the scope of the vulnerability since as of Safari 12.1, rel="noopener" is imposed on all target="_blank" links.

Following combination of smartbanner meta tags can be used to achieve the above:

```html
<meta name="smartbanner:enabled-platforms" content="none">
<meta name="smartbanner:include-user-agent-regex" content="Mobile.*Safari">
```
