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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"electron","product":"electron","versions":[{"version":"< 39.8.10","status":"affected"},{"version":">= 40.0.0-alpha.1, < 41.10.5","status":"affected"},{"version":">= 42.0.0-alpha.1, < 42.0.0-beta.2","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","baseScore":6.7,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":0.8,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-13T20:14:15.326288Z","id":"CVE-2026-102672","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-367"}]}],"references":[{"url":"https://github.com/electron/electron/commit/01faabfc250801a980fc94d64608046c67fc1cd9","source":"security-advisories@github.com"},{"url":"https://github.com/electron/electron/commit/15e2928a5c5f01759107b414010e220d90d59cef","source":"security-advisories@github.com"},{"url":"https://github.com/electron/electron/commit/a0f9ff4cc0340545008424232d49caadd9c0c767","source":"security-advisories@github.com"},{"url":"https://github.com/electron/electron/commit/b8f25c4cedb2e0f5f475912b709aba19c57c26be","source":"security-advisories@github.com"},{"url":"https://github.com/electron/electron/pull/50745","source":"security-advisories@github.com"},{"url":"https://github.com/electron/electron/releases/tag/v39.8.10","source":"security-advisories@github.com"},{"url":"https://github.com/electron/electron/releases/tag/v41.10.5","source":"security-advisories@github.com"},{"url":"https://github.com/electron/electron/releases/tag/v42.0.0-beta.2","source":"security-advisories@github.com"},{"url":"https://github.com/electron/electron/security/advisories/GHSA-vv43-5jgx-7qv8","source":"security-advisories@github.com"}]}
