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.","state":0,"publishedAt":"2026-08-05T16:17:04.617+00:00","modifiedAt":"2026-10-08T13:53:51.593+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:N/A:N","score":7.4,"severity":"HIGH"}],"references":["https://github.com/electron/electron/security/advisories/GHSA-v3j7-r9gq-3gjw"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-70604","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-942"],"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:*:*","cpe:2.3:a:electronjs:electron:42.0.0:beta3:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:beta4:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:beta5:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:beta6:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:beta7:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:42.0.0:beta8:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-08-05T16:17:04.617","lastModified":"2026-10-08T13:53:51.593"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
