Prior to 39.8.9, 40.9.2, 41.2.2, and 42.0.0-beta.5, apps that expose Promise-returning functions to web content via contextBridge may be vulnerable to a context isolation bypass. Untrusted web content could obtain access to the isolated preload world and, through it, every capability the preload script has. In renderers without a sandbox, or with nodeIntegration enabled, this may escalate to Node.js access. Apps are affected if they expose Promise-returning functions via contextBridge, the standard pattern for wrapping ipcRenderer.invoke, in windows that load untrusted content. This issue is fixed in versions 39.8.9, 40.9.2, 41.2.2, and 42.0.0-beta.5."}], "lastModified": "2026-10-08T13:54:09.117", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "11B2A013-C5C6-4DC6-9D7A-C20EFEB7E810", "versionEndExcluding": "39.8.9"}, {"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "52FF08D3-D405-4270-9C49-74247D2A3CB9", "versionEndExcluding": "40.9.2", "versionStartIncluding": "40.0.0"}, {"criteria": "cpe:2.3:a:electronjs:electron:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "3523AA34-7D59-4266-AFAF-D4B555947BD7", "versionEndExcluding": "41.2.2", "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"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
