Prior to 41.10.4, 42.5.2, and 43.0.0, popups opened from a sandboxed iframe through Electron's OpenURLFromTab navigation path, including links using target=\"_blank\" or a middle-click, did not receive the inherited HTML sandbox restrictions. An untrusted iframe using the allow-scripts allow-popups configuration could therefore open a popup with the embedding application's full origin, exposing that origin's cookies, storage, and same-origin scripting capabilities. Applications that do not embed untrusted content in sandboxed iframes are not affected. This issue is fixed in versions 41.10.4, 42.5.2, and 43.0.0.","state":0,"publishedAt":"2026-09-29T16:38:41.946+00:00","modifiedAt":"2026-09-30T20:11:08.29+00:00","affected":[{"ecosystem":"Vendor product","name":"electron","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"electron\",\n                    \"product\": \"electron\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 41.10.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 42.0.0-alpha.1, < 42.5.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 43.0.0-alpha.1, < 43.0.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","score":8.2,"severity":"HIGH"}],"references":["https://github.com/electron/electron/security/advisories/GHSA-hq2x-r82h-9wj4","https://github.com/electron/electron/pull/52133","https://github.com/electron/electron/commit/7ea14d5f55ecb11a30447701ddca16b3feee0bba","https://github.com/electron/electron/commit/e26b2640e7795c42bfb111b76009cbb4327c9a69","https://github.com/electron/electron/commit/ebe1165ee2b05c203c26dd2244ef1c5b9b1c04da","https://github.com/electron/electron/releases/tag/v41.10.4","https://github.com/electron/electron/releases/tag/v42.5.2","https://github.com/electron/electron/releases/tag/v43.0.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102673","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102673","identifiers":["CVE-2026-102673"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
