{"cve":"CVE-2025-25300","nvd":{"published":"2025-02-18T18:15:35.330","modified":"2026-06-17T09:00:38.680","status":"Deferred","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:L/SI:L/SA:N/E:U","score":1.3},"cvss_v3":null,"cwes":["CWE-79","CWE-601"],"references":["https://github.com/ain/smartbanner.js/commit/fce8c31dfe04033d9d005a89694d3e7a60784f89","https://github.com/ain/smartbanner.js/security/advisories/GHSA-9mrq-cjgh-32g2","https://github.com/ain/smartbanner.js/security/advisories/GHSA-9mrq-cjgh-32g2","https://github.com/ain/smartbanner.js/security/advisories/GHSA-9mrq-cjgh-32g2","https://github.com/ain/smartbanner.js/security/advisories/GHSA-9mrq-cjgh-32g2"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:59:18.731010617+00:00"},"epss":{"cve":"CVE-2025-25300","score":0.00419,"percentile":0.36249,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-9mrq-cjgh-32g2","url":"https://osv.dev/vulnerability/GHSA-9mrq-cjgh-32g2","summary":"smartbanner.js rel noopener vulnerability","modified":"2026-09-10T03:48:45.068645505Z","packages":[{"ecosystem":"npm","name":"smartbanner.js","purl":"pkg:npm/smartbanner.js","ranges":["<1.14.1"],"fixed":["1.14.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
