Prior to 39.8.9, 40.9.2, 41.2.1, and 42.0.0-beta.3, the DevTools reveal in file manager action could launch the target file rather than reveal it. An attacker with a separate means of running script inside the DevTools frontend, such as a malicious DevTools extension, could use showItemInFolder handling to execute native code outside the sandbox when DevTools is opened for windows exposed to untrusted content or untrusted DevTools extensions. This issue is fixed in 39.8.9, 40.9.2, 41.2.1, and 42.0.0-beta.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:N","score":6.9},"cwes":["CWE-78"],"references":["https://github.com/electron/electron/commit/10fb5b39c5287f70c4bbcab4c24197f3871ec322","https://github.com/electron/electron/commit/1b8a298d629d5a642c816ea5f7505359de17b771","https://github.com/electron/electron/commit/27bf1cae9274d5025684c7268496f435b7e06b44","https://github.com/electron/electron/commit/7a1eb7e5585991b3726cedb890a6244f327f43de","https://github.com/electron/electron/pull/50937"],"products":["electronjs:electron"],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-70611","score":0.00186,"percentile":0.0814,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-f2r8-jv7c-xqmp","url":"https://osv.dev/vulnerability/GHSA-f2r8-jv7c-xqmp","summary":"Electron: DevTools embedder handler executes arbitrary files via shell open","modified":"2026-08-05T18:11:04.120931Z","packages":[{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":["<39.8.9"],"fixed":["39.8.9"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=40.0.0-alpha.1 <40.9.2"],"fixed":["40.9.2"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=41.0.0-alpha.1 <41.2.1"],"fixed":["41.2.1"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=42.0.0-alpha.1 <42.0.0-beta.3"],"fixed":["42.0.0-beta.3"]}]}],"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).
