CVE-2026-103265: Incorrect Authorization in fleetdm fleet
Fleet versions before 4.89.0 fail to properly filter MDM command results by team authorization in the commands/results endpoint. Team-scoped users can read MDM command results for hosts on other teams when a shared command UUID targets hosts across multiple teams, exposing host UUIDs, command payloads, and device responses.
AI Analysis
Technical Summary
CVE-2026-103265 describes an incorrect authorization vulnerability in fleetdm's fleet product affecting versions before 4.89.0. The vulnerability arises because the commands/results endpoint does not properly filter MDM command results based on team authorization. Consequently, users scoped to a specific team can read MDM command results for hosts on other teams when a command UUID is shared across multiple teams. This leads to unauthorized disclosure of host UUIDs, command payloads, and device responses.
Potential Impact
Unauthorized users with team-scoped access can view sensitive MDM command results from hosts outside their authorized teams. This exposure includes host identifiers and device responses, potentially leading to information disclosure within the organization.
Mitigation Recommendations
Upgrade fleet to version 4.89.0 or later, where this authorization issue is fixed. Patch status is confirmed by the version boundary in the affectedVersions field. No additional vendor advisory was provided, so check official fleetdm resources for the patch details.
