{"id":"GHSA-9899-m83m-qhpj","summary":"Electron: USB device selection not validated against filtered device list","details":"### Impact\nThe `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`.\n\nThe 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.\n\n### Workarounds\nThere are no app side workarounds, you must update to a patched version of Electron.\n\n### Fixed Versions\n* `41.0.0-beta.8`\n* `40.7.0`\n* `39.8.0`\n* `38.8.6`\n\n### For more information\nIf there are any questions or comments about this advisory, send an email to [security@electronjs.org](mailto:security@electronjs.org)","aliases":["CVE-2026-34766"],"modified":"2026-04-06T23:18:50.163821Z","published":"2026-04-03T02:36:52Z","database_specific":{"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2026-04-03T02:36:52Z","nvd_published_at":"2026-04-04T00:16:17Z","cwe_ids":["CWE-862"]},"references":[{"type":"WEB","url":"https://github.com/electron/electron/security/advisories/GHSA-9899-m83m-qhpj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34766"},{"type":"PACKAGE","url":"https://github.com/electron/electron"}],"affected":[{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"38.8.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-9899-m83m-qhpj/GHSA-9899-m83m-qhpj.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"39.0.0-alpha.1"},{"fixed":"39.8.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-9899-m83m-qhpj/GHSA-9899-m83m-qhpj.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"40.0.0-alpha.1"},{"fixed":"40.7.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-9899-m83m-qhpj/GHSA-9899-m83m-qhpj.json"}},{"package":{"name":"electron","ecosystem":"npm","purl":"pkg:npm/electron"},"ranges":[{"type":"SEMVER","events":[{"introduced":"41.0.0-alpha.1"},{"fixed":"41.0.0-beta.8"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-9899-m83m-qhpj/GHSA-9899-m83m-qhpj.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N"}]}
