{"id":"CVE-2026-102672","published":"2026-10-13T16:17:09.343","lastModified":"2026-10-16T20:02:37.630","description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. 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.","cvssScore":6.7,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-367"],"vendors":[],"products":[],"references":[{"url":"https://github.com/electron/electron/commit/01faabfc250801a980fc94d64608046c67fc1cd9","tags":[]},{"url":"https://github.com/electron/electron/commit/15e2928a5c5f01759107b414010e220d90d59cef","tags":[]},{"url":"https://github.com/electron/electron/commit/a0f9ff4cc0340545008424232d49caadd9c0c767","tags":[]},{"url":"https://github.com/electron/electron/commit/b8f25c4cedb2e0f5f475912b709aba19c57c26be","tags":[]},{"url":"https://github.com/electron/electron/pull/50745","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v39.8.10","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v41.10.5","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v42.0.0-beta.2","tags":[]},{"url":"https://github.com/electron/electron/security/advisories/GHSA-vv43-5jgx-7qv8","tags":[]}],"exploitRefs":[{"url":"https://github.com/electron/electron/commit/01faabfc250801a980fc94d64608046c67fc1cd9","tags":[]},{"url":"https://github.com/electron/electron/commit/15e2928a5c5f01759107b414010e220d90d59cef","tags":[]},{"url":"https://github.com/electron/electron/commit/a0f9ff4cc0340545008424232d49caadd9c0c767","tags":[]},{"url":"https://github.com/electron/electron/commit/b8f25c4cedb2e0f5f475912b709aba19c57c26be","tags":[]},{"url":"https://github.com/electron/electron/pull/50745","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v39.8.10","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v41.10.5","tags":[]},{"url":"https://github.com/electron/electron/releases/tag/v42.0.0-beta.2","tags":[]},{"url":"https://github.com/electron/electron/security/advisories/GHSA-vv43-5jgx-7qv8","tags":[]}],"hasPoc":true,"ai":null}
