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.","evidence":"cve:CVE-2026-102673","products":[{"name":{"value":"electron","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"high","structured":{"id":"CVE-2026-102673","aliases":["CVE-2026-102673"],"metrics":[{"cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":8.2,"attackVector":"NETWORK","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","integrityImpact":"LOW","userInteraction":"REQUIRED","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"electron","product":"electron","versions":[{"status":"affected","version":"< 41.10.4"},{"status":"affected","version":">= 42.0.0-alpha.1, < 42.5.2"},{"status":"affected","version":">= 43.0.0-alpha.1, < 43.0.0"}]}],"modified":"2026-09-30T20:11:08.290Z","provider":"cve","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"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-102673","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-30T19:34:09.694143Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-30T20:11:08.290Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-29T16:38:41.946Z"}}},"related_cves":[{"value":"CVE-2026-102673","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":4892,"next_before":4892}
