Information disclosure in Fleet Apple MDM commands listing endpoint

IdentifiersCVE-2026-46371CWE-89

CVE-2026-46371 is an observer-level information disclosure vulnerability in Fleet affecting the Apple MDM commands listing endpoint, GET /api/v1/fleet/mdm/apple/commands. According to the provided advisory, the endpoint fails to properly validate the order_key parameter used for sorting, enabling an authenticated low-privilege user with the Observer role to abuse the ORDER BY clause as an oracle. By leveraging cursor-based binary search against joined database tables, an attacker can infer and extract sensitive values that should not be exposed through this endpoint. Reported exposed data includes host enrollment secrets, node_key, orbit_node_key, and APNS tokens.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a low-privilege authenticated Observer to disclose sensitive Fleet-managed secrets and tokens from backend data sources. Exposure of node_key or orbit_node_key can enable host impersonation against Fleet's osquery and Orbit endpoints, allowing submission of fabricated host data and retrieval of pending scripts and commands intended for enrolled hosts. Disclosure of APNS tokens may further support abuse of Apple MDM-related functionality, although use of those tokens additionally requires possession of the organization's APNS certificate.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, limit the Observer role to fully trusted users until the fix is deployed. For any hosts potentially affected, rotate exposed node_key and orbit_node_key values by re-enrolling those hosts. Review access to Apple MDM-related secrets and consider incident response actions if APNS tokens or enrollment secrets are suspected to have been exposed.

Remediation

Patch, then assume compromise.

Upgrade Fleet to version 4.84.2 or later, which addresses the vulnerable handling of the order_key parameter in the Apple MDM commands listing endpoint.
