{"id":"CVE-2026-102672","aliases":["GHSA-vv43-5jgx-7qv8"],"url":"https://o3.security/vulnerability/CVE-2026-102672","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)","published":"2026-10-13T15:52:46.436Z","modified":"2026-10-24T02:30:33.608962323Z","cvss":{"score":6.7,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"electron","fixedVersion":"39.8.10"},{"ecosystem":"npm","name":"electron","fixedVersion":"41.10.5"},{"ecosystem":"npm","name":"electron","fixedVersion":"42.0.0-beta.2"}],"fix":{"url":"https://github.com/electron/electron/commit/01faabfc250801a980fc94d64608046c67fc1cd9","label":"electron/electron@01faabf"},"references":[{"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"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/102xxx/CVE-2026-102672.json"},{"type":"ADVISORY","url":"https://github.com/electron/electron/security/advisories/GHSA-vv43-5jgx-7qv8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102672"},{"type":"FIX","url":"https://github.com/electron/electron/commit/01faabfc250801a980fc94d64608046c67fc1cd9"},{"type":"FIX","url":"https://github.com/electron/electron/commit/15e2928a5c5f01759107b414010e220d90d59cef"},{"type":"FIX","url":"https://github.com/electron/electron/commit/a0f9ff4cc0340545008424232d49caadd9c0c767"},{"type":"FIX","url":"https://github.com/electron/electron/commit/b8f25c4cedb2e0f5f475912b709aba19c57c26be"},{"type":"FIX","url":"https://github.com/electron/electron/pull/50745"},{"type":"PACKAGE","url":"https://github.com/electron/electron"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-24T02:30:33.608962323Z"}}
