Prior to 41.10.6, 42.9.2, 43.4.1, and 44.0.0-beta.5, an Electron <webview> guest could enable nodeIntegrationInWorker for its Web Workers even when the unsandboxed embedder had Node.js integration disabled, allowing untrusted guest content to create a Node-enabled worker with more privilege than the embedder granted. Applications that do not enable the <webview> tag or that keep the embedder sandboxed are not affected. This issue is fixed in versions 41.10.6, 42.9.2, 43.4.1, and 44.0.0-beta.5.","state":0,"publishedAt":"2026-09-29T16:56:49.007+00:00","modifiedAt":"2026-09-29T19:50:28.382+00:00","affected":[{"ecosystem":"Vendor product","name":"electron","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"electron\",\n                    \"product\": \"electron\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 41.10.6\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 42.0.0-alpha.1, < 42.9.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 43.0.0-alpha.1, < 43.4.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 44.0.0-alpha.1, < 44.0.0-beta.5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","score":8.3,"severity":"HIGH"}],"references":["https://github.com/electron/electron/security/advisories/GHSA-9qh4-3jw8-366w","https://github.com/electron/electron/commit/6462a2e1dc4e6adffd3b7d9b9be1474c45dcbbe2","https://github.com/electron/electron/commit/9a675aef8822bae4088567822969f900b3a37671","https://github.com/electron/electron/commit/b3ae0aab5cf81c2ed03d04df1ae8e69ecfab7886","https://github.com/electron/electron/commit/cd34f335c8664613db5b6e61ae51e2e1846233ae","https://github.com/electron/electron/releases/tag/v41.10.6","https://github.com/electron/electron/releases/tag/v42.9.2","https://github.com/electron/electron/releases/tag/v43.4.1","https://github.com/electron/electron/releases/tag/v44.0.0-beta.5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102676","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102676","identifiers":["CVE-2026-102676"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
