CVE-2025-25300
February 18, 2025
smartbanner.js is a customizable smart app banner for iOS and Android. Prior to version 1.14.1, clicking on smartbanner "View" link and navigating to 3rd party page leaves "window.opener" exposed. It may allow hostile third parties to abuse "window.opener", e.g. by redirection or injection on the original page with smartbanner. "rel="noopener"" is automatically populated to links as of "v1.14.1" which is a recommended upgrade to resolve the vulnerability. Some workarounds are available for those who cannot upgrade. Ensure "View" link is only taking users to App Store or Google Play Store where security is guarded by respective app store security teams. If "View" link is going to a third 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. Version 1.14.1 of smartbanner.js contains a fix for the issue.
