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."}], "lastModified": "2026-10-15T14:01:06.497", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "94E93D1A-EB27-460E-8A0E-C3D6AD775994", "versionEndExcluding": "39.8.8"}, {"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "56E4CE6E-6A00-4DF6-A720-141D67D4CA2D", "versionEndExcluding": "40.9.0", "versionStartIncluding": "40.0.0"}, {"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "751C3E3A-F353-4132-B199-92C1FD547F31", "versionEndIncluding": "41.2.1", "versionStartIncluding": "41.0.0"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha1:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "498062D8-5C83-4FC2-A04B-94F3228B2BED"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha2:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "A272F9F4-AB62-407C-B1A8-18586A474C19"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha3:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "BF49E260-9653-4D26-8B6C-C6FAFE697F5A"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha4:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "2F3B609A-0CA5-4E8C-865E-CF79B6B0CCCC"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha5:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "308A710A-7965-40A0-87E4-2B66A8CEF87A"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:alpha6:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "6CFEB6F4-A38A-43BC-92B1-2E1DC8BBD1D7"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:beta1:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "7B9FD9F4-48E0-4EA2-957D-57ADA2A3D42A"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:beta2:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "62E12D3F-154E-44AB-919F-0E34E970C2CB"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
