Prior to 41.10.4, 42.5.2, and 43.0.0, popups opened from a sandboxed iframe through Electron's OpenURLFromTab navigation path, including links using target=\"_blank\" or a middle-click, did not receive the inherited HTML sandbox restrictions. An untrusted iframe using the allow-scripts allow-popups configuration could therefore open a popup with the embedding application's full origin, exposing that origin's cookies, storage, and same-origin scripting capabilities. Applications that do not embed untrusted content in sandboxed iframes are not affected. This issue is fixed in versions 41.10.4, 42.5.2, and 43.0.0.","state":0,"publishedAt":"2026-09-29T17:17:07.487+00:00","modifiedAt":"2026-10-15T14:01:06.497+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","score":8.2,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1,"severity":"MEDIUM"}],"references":["https://github.com/electron/electron/commit/7ea14d5f55ecb11a30447701ddca16b3feee0bba","https://github.com/electron/electron/commit/e26b2640e7795c42bfb111b76009cbb4327c9a69","https://github.com/electron/electron/commit/ebe1165ee2b05c203c26dd2244ef1c5b9b1c04da","https://github.com/electron/electron/pull/52133","https://github.com/electron/electron/releases/tag/v41.10.4","https://github.com/electron/electron/releases/tag/v42.5.2","https://github.com/electron/electron/releases/tag/v43.0.0","https://github.com/electron/electron/security/advisories/GHSA-hq2x-r82h-9wj4"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-102673","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-346","CWE-693"],"productCriteria":["cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:alpha1:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:alpha2:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:alpha3:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:alpha4:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:alpha5:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:alpha6:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:beta1:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:beta2:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-09-29T17:17:07.487","lastModified":"2026-10-15T14:01:06.497"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
