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.","evidence":"cve:CVE-2026-102672","products":[{"name":{"value":"electron","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-102672","aliases":["CVE-2026-102672"],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":6.7,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"REQUIRED","attackComplexity":"HIGH","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}}],"affected":[{"vendor":"electron","product":"electron","versions":[{"status":"affected","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"}]}],"modified":"2026-10-13T20:22:22.127Z","provider":"cve","references":["https://github.com/electron/electron/security/advisories/GHSA-vv43-5jgx-7qv8","https://github.com/electron/electron/pull/50745","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/releases/tag/v39.8.10","https://github.com/electron/electron/releases/tag/v41.10.5","https://github.com/electron/electron/releases/tag/v42.0.0-beta.2"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-102672","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-10-13T20:14:15.326288Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-13T20:22:22.127Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-10-13T15:52:46.436Z"}}},"related_cves":[{"value":"CVE-2026-102672","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":20786,"next_before":20786}
