CVE-2026-101046: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in fleetdm fleet
Fleet versions prior to 4.89.0 contain an SQL injection vulnerability in the activity list endpoints. This vulnerability allows an authenticated user with read access to the Activity resource to influence the SQL ORDER BY clause via a sort/order key without proper allowlisting. The impact is limited to read-only inference of certain columns in the activity_past table that are not normally exposed. There is no write access, privilege escalation, or access to sensitive host-related data through this flaw. The issue is fixed in version 4.89.0 by removing the deprecated helper and sanitizing the sort column input.
AI Analysis
Technical Summary
Fleet before version 4.89.0 has an SQL injection vulnerability in the GET /api/v1/fleet/activities and GET /api/v1/fleet/hosts/{id}/activities endpoints. The deprecated cursor-pagination helper appendListOptionsWithCursorToSQL interpolated user-supplied sort/order keys directly into the SQL ORDER BY clause without an allowlist, enabling an authenticated user with read access to order results by arbitrary columns. This allows inference of values from columns in the activity_past table that are not otherwise returned in the API responses. The vulnerability does not permit write operations, privilege escalation, or access to sensitive host-join columns such as node_key. The vulnerability is resolved in version 4.89.0 by removing the deprecated helper and sanitizing the sort column parameter.
Potential Impact
An authenticated user with read access to Activity can exploit this vulnerability to infer values from certain columns in the activity_past table that are not normally exposed. The impact is read-only and limited to information disclosure through sorting behavior. There is no ability to modify data, escalate privileges, or access sensitive host-related information via this vulnerability.
Mitigation Recommendations
This vulnerability is fixed in Fleet version 4.89.0. Users should upgrade to version 4.89.0 or later to remediate this issue. No other mitigation is required as the fix removes the vulnerable helper and sanitizes the sort column input.
