Prior to 39.8.8, 40.9.0, 41.2.1, and 42.0.0-beta.3, the native autofill popup could be positioned by a cross-origin iframe outside that iframe's bounds, over the embedding page's UI, enabling clickjacking or spoofing of trusted UI. Apps are only affected if they embed untrusted content in iframes within windows that also display trusted UI. Apps that do not embed untrusted third-party content … CWE-1021Aug 5, 2026 | CVSS3.1v3.1 | EPSS0.136% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
CVE-2026-70599MEDIUM | Electron: Permission Check Handler Receives Main Frame Origin Instead of Requesting Iframe OriginElectron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1, serial-port and media permission checks made from an iframe passed the top-level frame origin to session.setPermissionCheckHandler instead of the requesting iframe origin. Origin-based handler logic could grant a cross-origin iframe device access intended only for the top-level origin. This issue is fixed in 39.8.7, 40.9.0, 41.2.0, and 42.0.0… CWE-346Aug 5, 2026 | CVSS5.9v3.1 | EPSS0.142% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
Electron: Off-screen rendering trusts GPU-supplied geometry over shared-memory sizeElectron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.10, 40.9.0, 41.2.1, and 42.0.0-beta.3, offscreen rendering frame data received from the GPU process was not fully validated by the main process. A compromised GPU process could cause the main process to read out-of-bounds memory while producing paint event images, disclosing memory or crashing the app. This issue is fixed in 39.8.10, 40.9.0, 41.2.1, and 42.0.0-beta.3.
