{"schema":"threatline.record/2","record":{"id":"CVE-2026-102674","aliases":["GHSA-gr2m-v5gq-v685"],"summary":"Electron: Windows opened from a sandboxed top-level document do not inherit its sandbox restrictions","details":"### Impact\n\nWindows opened from a sandboxed top-level document did not inherit that document's HTML `sandbox` restrictions, so content that was meant to run sandboxed could open a window with the app's full origin. GHSA-hq2x-r82h-9wj4 covers the same issue for sandboxed iframes.\n\nApps are only affected if they render untrusted content in a sandboxed top-level document that allows popups. Apps that deny popups from untrusted content with `setWindowOpenHandler` are not affected.\n\n### Workarounds\n\nReturn `{ action: 'deny' }` from `setWindowOpenHandler` for windows opened by untrusted content.\n\n### Fixed Versions\n\n* `44.0.0-beta.5`\n* `43.4.1`\n* `42.9.2`\n* `41.10.6`\n\n### For more information\n\nIf you have any questions or comments about this advisory, email us at
