{"cve":"CVE-2026-34766","nvd":{"published":"2026-04-04T00:16:17.140","modified":"2026-07-24T22:10:00.140","status":"Analyzed","description":"Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8, the select-usb-device event callback did not validate the chosen device ID against the filtered list that was presented to the handler. An app whose handler could be influenced to select a device ID outside the filtered set would grant access to a device that did not match the renderer's requested filters or was listed in exclusionFilters. The WebUSB security blocklist remained enforced regardless, so security-sensitive devices on the blocklist were not affected. The practical impact is limited to apps with unusual device-selection logic. This issue has been patched in versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-862"],"references":["https://github.com/electron/electron/security/advisories/GHSA-9899-m83m-qhpj"],"products":["electronjs:electron"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-34766","score":0.00165,"percentile":0.05689,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9899-m83m-qhpj","url":"https://osv.dev/vulnerability/GHSA-9899-m83m-qhpj","summary":"Electron: USB device selection not validated against filtered device list","modified":"2026-04-06T23:18:50.163821Z","packages":[{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":["<38.8.6"],"fixed":["38.8.6"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=39.0.0-alpha.1 <39.8.0"],"fixed":["39.8.0"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=40.0.0-alpha.1 <40.7.0"],"fixed":["40.7.0"]},{"ecosystem":"npm","name":"electron","purl":"pkg:npm/electron","ranges":[">=41.0.0-alpha.1 <41.0.0-beta.8"],"fixed":["41.0.0-beta.8"]}]}],"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).
