Summary
Fleet up to version 4.84.1 contains a vulnerability in the Apple MDM commands listing endpoint (GET /api/v1/fleet/mdm/apple/commands) that allows an authenticated user with the Observer role to extract sensitive values such as host enrollment secrets and APNs tokens via a sort-order oracle. An attacker can manipulate the order_key parameter and use binary search to reconstruct values character by character. Fixed in version 4.84.2.
Risk Assessment
Disclosure of enrollment secrets and APNs tokens may allow an attacker to impersonate enrolled hosts, submit fabricated data, and retrieve scripts and commands.
Recommendation
Update Fleet to version 4.84.2 or later.
Other vulnerabilities in Fleet
See all- CVE-2026-54245High
Fleet is an open-source device management platform. In versions prior to 4.86.2, the Okta conditional access integration in Fleet Premium is vulnerable to SQL injection through a host-supplied value used in a database query without proper parameterization, allowing an attacker controlling one enrolled host to read or modify arbitrary data in the Fleet database. By disclosing arbitrary database contents, an attacker can extract stored session tokens and replay them to act as a global administrator, and on a managed fleet that administrator access enables running scripts on enrolled hosts, leading to remote code execution.
- CVE-2026-46370Medium
Fleet up to version 4.84.1 contains a vulnerability in the labels host-listing endpoint (GET /api/v1/fleet/labels/{id}/hosts) that allows an authenticated user with the Observer role to extract host enrollment secrets via a sort-order oracle. An attacker can manipulate the order_key parameter and reconstruct node_key or orbit_node_key, enabling host impersonation. Fixed in version 4.84.2.
- CVE-2026-48786Medium
Fleet prior to version 4.87.0 contains a vulnerability in the target search endpoint (POST /api/latest/fleet/targets) that returns unmasked team enroll secrets and full team configuration, including credential-bearing agent options, to low-privilege observer-class users. Fixed in version 4.87.0.
- CVE-2026-41262Medium
Fleet prior to version 4.85.0 contains a vulnerability in the global policy read endpoint (GET /api/latest/fleet/policies/{policy_id}) that fails to verify team ownership of the requested policy, allowing an authenticated user with observer-level access on any single team to read the full details of policies belonging to any other team. Fixed in version 4.85.0.
- CVE-2026-44938High
A vulnerability in Fleet allows an attacker with git push access to overwrite Pod Security Standards (PSS) enforcement labels on a target namespace. This occurs because the agent-side deployer does not filter security-sensitive keys from namespaceLabels in fleet.yaml.
Original NVD description (English source)
Fleet is an open-source device management platform built on osquery. In versions up to and including 4.84.1, the Apple MDM commands listing endpoint (GET /api/v1/fleet/mdm/apple/commands) allowed an authenticated user with the lowest-privilege Observer role to extract sensitive values from joined database tables, including host enrollment secrets and Apple Push Notification Service tokens, through a sort-order oracle. The endpoint accepted a user-supplied order_key parameter that was not validated against a column allowlist, and because the underlying query joins the hosts and nano_enrollments tables, an attacker could set the sort column to a sensitive field and combine it with the cursor-based after parameter to binary-search the value one character at a time, with the presence or absence of results revealing each character even though the value never appeared in the response. With extracted node_key or orbit_node_key values an attacker could impersonate enrolled hosts to Fleet's osquery and Orbit endpoints, submit fabricated host data, and retrieve pending scripts and commands. This issue is fixed in version 4.84.2.
