{"id":"GHSA-vv43-5jgx-7qv8","summary":"Electron: Local race condition in Squirrel.Mac update installation on macOS","details":"### Impact\n\nOn macOS, Electron bundles the Squirrel.Mac auto-update framework, whose privileged `ShipIt` helper performs the final step of an update as root. A local attacker could cause that helper to overwrite a different application's files, as root, instead of the app that started the update. Exploitation requires local access to the machine.\n\nApps are only affected on macOS if they ship Squirrel.Mac-based auto-updates. Apps on other platforms, or that do not use Squirrel.Mac auto-updates, are not affected.\n\n### Workarounds\n\nThere are no app side workarounds, you must update to a patched version of Electron.\n\n### Fixed Versions\n\n* `42.0.0-beta.2`\n* `41.10.5`\n* `39.8.10`\n\n### For more information\n\nIf you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)","aliases":["CVE-2026-102672"],"modified":"2026-09-29T18:15:05.576764582Z","published":"2026-09-29T18:06:59Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-09-29T18:06:59Z","nvd_published_at":null,"cwe_ids":["CWE-367"]},"references":[{"type":"WEB","url":"https://github.com/electron/electron/security/advisories/GHSA-vv43-5jgx-7qv8"},{"type":"WEB","url":"https://github.com/electron/electron/pull/50745"},{"type":"WEB","url":"https://github.com/electron/electron/commit/01faabfc250801a980fc94d64608046c67fc1cd9"},{"type":"WEB","url":"https://github.com/electron/electron/commit/15e2928a5c5f01759107b414010e220d90d59cef"},{"type":"WEB","url":"https://github.com/electron/electron/commit/a0f9ff4cc0340545008424232d49caadd9c0c767"},{"type":"WEB","url":"https://github.com/electron/electron/commit/b8f25c4cedb2e0f5f475912b709aba19c57c26be"},{"type":"PACKAGE","url":"https://github.com/electron/electron"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v39.8.10"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v41.10.5"},{"type":"WEB","url":"https://github.com/electron/electron/releases/tag/v42.0.0-beta.2"}],"affected":[{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"39.8.10"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-vv43-5jgx-7qv8/GHSA-vv43-5jgx-7qv8.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"40.0.0-alpha.1"},{"fixed":"41.10.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-vv43-5jgx-7qv8/GHSA-vv43-5jgx-7qv8.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"42.0.0-alpha.1"},{"fixed":"42.0.0-beta.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-vv43-5jgx-7qv8/GHSA-vv43-5jgx-7qv8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H"}]}
