"summary": "Electron: USB device selection not validated against filtered device list",
10+
"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)",
