Detailsinfo

A vulnerability was found in FleetDM Fleet up to 4.86.1. It has been rated as critical. This issue affects an unknown code of the component Okta Conditional Access Integration. The manipulation with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Fleet is an open-source device management platform built on osquery. 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 that is used in a database query without proper parameterization, allowing an attacker who controls a single enrolled host to read or modify arbitrary data in the Fleet database. The value is reported by the host's own agent and stored verbatim, then used on an unauthenticated request path that supports the conditional access integration, so any party controlling one enrolled host, the lowest-privilege position in the product, can influence the query. 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. The issue requires Fleet Premium with the Okta conditional access integration enabled and does not affect instances where it is not configured. This issue is fixed in version 4.86.2.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-54245 since 06/12/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1505 for this issue.

Upgrading to version 4.86.2 eliminates this vulnerability.
