{"id":"GHSA-xwr5-m59h-vwqr","summary":"Electron: nodeIntegrationInWorker not correctly scoped in shared renderer processes","details":"### Impact\nThe `nodeIntegrationInWorker` webPreference was not correctly scoped in all configurations. In certain process-sharing scenarios, workers spawned in frames configured with `nodeIntegrationInWorker: false` could still receive Node.js integration.\n\nApps are only affected if they enable `nodeIntegrationInWorker`. Apps that do not use `nodeIntegrationInWorker` are not affected.\n\n### Workarounds\nAvoid enabling `nodeIntegrationInWorker` in apps that also open child windows or embed content with differing webPreferences.\n\n### Fixed Versions\n* `41.0.0`\n* `40.8.4`\n* `39.8.4`\n* `38.8.6`\n\n### For more information\nIf there are any questions or comments about this advisory, please email [security@electronjs.org](mailto:security@electronjs.org)","aliases":["CVE-2026-34775"],"modified":"2026-04-06T23:20:06.134110Z","published":"2026-04-03T02:43:05Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-04-03T02:43:05Z","nvd_published_at":"2026-04-04T00:16:18Z","cwe_ids":["CWE-653"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/electron/electron/security/advisories/GHSA-xwr5-m59h-vwqr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34775"},{"type":"PACKAGE","url":"https://github.com/electron/electron"}],"affected":[{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"38.8.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-xwr5-m59h-vwqr/GHSA-xwr5-m59h-vwqr.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"39.0.0-alpha.1"},{"fixed":"39.8.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-xwr5-m59h-vwqr/GHSA-xwr5-m59h-vwqr.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"40.0.0-alpha.1"},{"fixed":"40.8.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-xwr5-m59h-vwqr/GHSA-xwr5-m59h-vwqr.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"41.0.0-alpha.1"},{"fixed":"41.0.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-xwr5-m59h-vwqr/GHSA-xwr5-m59h-vwqr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N"}]}
