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.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:L/A:N","score":7.5,"severity":null}],"references":["https://github.com/electron/electron/security/advisories/GHSA-h7rp-cf8h-j98x"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-53433","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 5, 2026, 3:45:31 PM","dateUpdated":"Aug 5, 2026, 5:30:28 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
