From 42.3.3 until 42.10.0, 43.5.0, and 44.0.0-beta.6, Electron's sandboxed preload code cache did not verify that a cached entry matched the preload it was served for. A compromised renderer could write attacker-controlled cache data and cause Electron to reuse it for a later load, executing the renderer's code in the more privileged preload context. The issue affects applications that load untrusted content. This issue is fixed in versions 42.10.0, 43.5.0, and 44.0.0-beta.6.","state":0,"publishedAt":"2026-09-29T18:17:09.573+00:00","modifiedAt":"2026-10-08T20:24:30.737+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","score":7.8,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/electron/electron/commit/000453e399bd1dee5e86376cdd9ece5fc071e601","https://github.com/electron/electron/commit/25ba8be57c65a83d8c14ebb8aa37693df17a04f3","https://github.com/electron/electron/commit/c38d6fd68756f04647ea857bdb6a2abec332e217","https://github.com/electron/electron/pull/52480","https://github.com/electron/electron/releases/tag/v42.10.0","https://github.com/electron/electron/releases/tag/v43.5.0","https://github.com/electron/electron/releases/tag/v44.0.0-beta.6","https://github.com/electron/electron/security/advisories/GHSA-qmv3-fv6v-rmhq"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-102677","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-20","CWE-345"],"productCriteria":["cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:alpha1:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:alpha2:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:alpha3:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:alpha4:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:alpha5:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:alpha6:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:alpha7:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:alpha8:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:alpha9:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:beta1:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:beta2:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:beta3:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:beta4:*:*:*:node.js:*:*","cpe:2.3:a:electronjs:electron:44.0.0:beta5:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-09-29T18:17:09.573","lastModified":"2026-10-08T20:24:30.737"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
