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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-269","CWE-1188"],"references":["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"],"products":["electronjs:electron"],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-102676","score":0.00479,"percentile":0.41035,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-9qh4-3jw8-366w","url":"https://osv.dev/vulnerability/GHSA-9qh4-3jw8-366w","summary":"Electron: <webview> can enable Node.js integration in Web Workers despite embedder restrictions","modified":"2026-09-29T18:15:04.717504273Z","packages":[{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":["<41.10.6"],"fixed":["41.10.6"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=42.0.0-alpha.1 <42.9.2"],"fixed":["42.9.2"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=43.0.0-alpha.1 <43.4.1"],"fixed":["43.4.1"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=44.0.0-alpha.1 <44.0.0-beta.5"],"fixed":["44.0.0-beta.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
