{"id":"CVE-2026-105664","kind":"vulnerability","aliases":["CVE-2026-105664"],"related":[],"title":"Endpoint leaks which device IDs are registered through differing error codes","description":"The endpoint exposes an observable response discrepancy when processing ID values. A request submitted with a nonexistent ID returns a distinct error response code from one submitted with a valid, registered ID, allowing an attacker holding a valid access token - but without further authentication or authorization - to distinguish valid ID values from the full 10-digit numeric search space. Combined with the absence of meaningful rate limiting on this endpoint, this discrepancy constitutes an enumeration oracle, enabling an attacker to discover registered devices at scale.","summary":"The endpoint returns a different error code for nonexistent IDs than for valid registered IDs. An attacker with any valid access token can use this to enumerate registered devices across the 10-digit ID space, since rate limiting is weak.","severity":"medium","cvss":6.9,"epss":null,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["api","device-registry","other"],"not_affected_if":[],"how_to_check":null,"fix":null,"status":"open","published_at":"2026-10-16T14:17:14+00:00","first_seen_at":"2026-10-23T21:57:13+00:00","triaged_at":"2026-10-25T03:42:30+00:00","updated_at":"2026-10-25T03:42:30+00:00","category":"other","confidence":0.4,"triage":{"at":"2026-10-25T03:42:30Z","model":"claude-haiku-5-5","output":{"fix":"unknown","reach":"internet","title":"Endpoint leaks which device IDs are registered through differing error codes","impact":"low","summary":"The endpoint returns a different error code for nonexistent IDs than for valid registered IDs.
