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.","state":0,"publishedAt":"2026-10-13T15:52:46.436+00:00","modifiedAt":"2026-10-13T20:22:22.127+00:00","affected":[{"ecosystem":"Vendor product","name":"electron","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"electron\",\n                    \"product\": \"electron\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 39.8.10\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 40.0.0-alpha.1, < 41.10.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 42.0.0-alpha.1, < 42.0.0-beta.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"MEDIUM"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102672","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102672","identifiers":["CVE-2026-102672"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
