Prior to 39.8.10, 41.10.5, and 42.0.0-beta.2, Electron applications on macOS that use Squirrel.Mac-based automatic updates are vulnerable to a local race in the privileged ShipIt helper. The helper did not bind the validated update target to one canonical application-bundle path for the full installation, allowing a local attacker to redirect the root-level write so that it overwrites another application's files instead of the application that initiated the update. Applications on other platforms and macOS applications that do not use Squirrel.Mac-based automatic updates are not affected. This issue is fixed in versions 39.8.10, 41.10.5, and 42.0.0-beta.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","score":6.7},"cwes":["CWE-367"],"references":["https://github.com/electron/electron/commit/01faabfc250801a980fc94d64608046c67fc1cd9","https://github.com/electron/electron/commit/15e2928a5c5f01759107b414010e220d90d59cef","https://github.com/electron/electron/commit/a0f9ff4cc0340545008424232d49caadd9c0c767","https://github.com/electron/electron/commit/b8f25c4cedb2e0f5f475912b709aba19c57c26be","https://github.com/electron/electron/pull/50745"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-102672","score":0.00093,"percentile":0.00529,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-vv43-5jgx-7qv8","url":"https://osv.dev/vulnerability/GHSA-vv43-5jgx-7qv8","summary":"Electron: Local race condition in Squirrel.Mac update installation on macOS","modified":"2026-09-29T18:15:05.576764582Z","packages":[{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":["<39.8.10"],"fixed":["39.8.10"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=40.0.0-alpha.1 <41.10.5"],"fixed":["41.10.5"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=42.0.0-alpha.1 <42.0.0-beta.2"],"fixed":["42.0.0-beta.2"]}]}],"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).
