{"id":"CVE-2026-34766","aliases":["GHSA-9899-m83m-qhpj"],"url":"https://o3.security/vulnerability/CVE-2026-34766","summary":"Electron: USB device selection not validated against filtered device list","details":"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.","published":"2026-04-03T23:35:10.204Z","modified":"2026-08-07T21:14:27.952352Z","cvss":{"score":3.3,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"electron","fixedVersion":"38.8.6"},{"ecosystem":"npm","name":"electron","fixedVersion":"39.8.0"},{"ecosystem":"npm","name":"electron","fixedVersion":"40.7.0"},{"ecosystem":"npm","name":"electron","fixedVersion":"41.0.0-beta.8"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34766.json"},{"type":"ADVISORY","url":"https://github.com/electron/electron/security/advisories/GHSA-9899-m83m-qhpj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34766"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T21:14:27.952352Z"}}
