Prior to 39.8.10, 40.9.3, 41.4.0, and 42.0.0, a custom scheme registered with supportFetchAPI: true but without corsEnabled: true was not subject to CORS enforcement. A page loaded from a remote origin could therefore fetch() or XMLHttpRequest that scheme cross-origin and read the full response body, rather than the read being blocked. Apps that serve sensitive data from such a scheme and load remote or untrusted content in a renderer are affected. This issue is fixed in versions 39.8.10, 40.9.3, 41.4.0, and 42.0.0."}], "lastModified": "2026-10-08T13:53:51.593", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "6038A7D4-16F2-4940-AA5B-E5235C86FEEA", "versionEndExcluding": "39.8.10"}, {"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "6F474638-6FCC-4E25-A641-6E3B57BEFD55", "versionEndExcluding": "40.9.3", "versionStartIncluding": "40.0.0"}, {"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "2CD7048D-1D1D-41BF-AC8C-A17CF85ADFBC", "versionEndExcluding": "41.4.0", "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"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:beta3:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "1860288A-C1FE-47A4-9C05-FD8EDDCE7093"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:beta4:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "83C96449-AF09-442A-BE4C-39A298557337"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:beta5:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "5AED130C-260D-47AA-8A07-11A5AC310E36"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:beta6:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "5E6EB469-107E-4A62-9C89-1BD90B6C8263"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:beta7:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "01C12A55-5CE8-48E7-8F91-52A574D4C39A"}, {"criteria": "cpe:2.3:a:electronjs:electron:42.0.0:beta8:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "1686FF0B-11E1-464D-99D7-32C46D922D10"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
