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-beta.1.","state":0,"publishedAt":"2026-08-05T15:36:02.182+00:00","modifiedAt":"2026-08-05T18:41:57.567+00:00","affected":[{"ecosystem":"Vendor product","name":"electron","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"electron\",\n                    \"product\": \"electron\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 39.8.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 40.0.0-alpha.1, < 40.9.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 41.0.0-alpha.1, < 41.2.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 42.0.0-alpha.1, < 42.0.0-beta.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9,"severity":"MEDIUM"}],"references":["https://github.com/electron/electron/security/advisories/GHSA-9pf5-hg6p-4pwp","https://github.com/electron/electron/commit/0cbdf2f0375466d701aa393c92e0ec29eb89ea6c"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-70599","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-70599","identifiers":["CVE-2026-70599"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
