{"id":"CVE-2026-102676","published":"2026-09-29T17:17:07.973","lastModified":"2026-09-29T20:17:17.243","description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. 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.","cvssScore":8.3,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","cwes":["CWE-269","CWE-1188"],"vendors":[],"products":[],"references":[{"url":"https://github.com/electron/electron/commit/6462a2e1dc4e6adffd3b7d9b9be1474c45dcbbe2","tags":[]},{"url":"https://github.com/electron/electron/commit/9a675aef8822bae4088567822969f900b3a37671","tags":[]},{"url":"https://github.com/electron/electron/commit/b3ae0aab5cf81c2ed03d04df1ae8e69ecfab7886","tags":[]},{"url":"https://github.com/electron/electron/commit/cd34f335c8664613db5b6e61ae51e2e1846233ae","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v41.10.6","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v42.9.2","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v43.4.1","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v44.0.0-beta.5","tags":[]},{"url":"https://github.com/electron/electron/security/advisories/GHSA-9qh4-3jw8-366w","tags":[]}],"exploitRefs":[{"url":"https://github.com/electron/electron/commit/6462a2e1dc4e6adffd3b7d9b9be1474c45dcbbe2","tags":[]},{"url":"https://github.com/electron/electron/commit/9a675aef8822bae4088567822969f900b3a37671","tags":[]},{"url":"https://github.com/electron/electron/commit/b3ae0aab5cf81c2ed03d04df1ae8e69ecfab7886","tags":[]},{"url":"https://github.com/electron/electron/commit/cd34f335c8664613db5b6e61ae51e2e1846233ae","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v41.10.6","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v42.9.2","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v43.4.1","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v44.0.0-beta.5","tags":[]},{"url":"https://github.com/electron/electron/security/advisories/GHSA-9qh4-3jw8-366w","tags":[]}],"hasPoc":true,"ai":null}
