Description
Summary
A SQL injection vulnerability in Fleet's Okta conditional access integration could allow an attacker who controls a single enrolled host to read or modify arbitrary data in the Fleet database, including stored session tokens. Disclosed session tokens may be replayed to act as a global administrator, which on a managed fleet leads to remote code execution on enrolled hosts.
Impact
When Fleet Premium with Okta conditional access is configured, an unauthenticated request path that supports the conditional access integration uses a host-supplied value in a database query without proper parameterization. Because the value is reported by the host's own agent and stored verbatim, any party that controls one enrolled host (the lowest-privilege role in the product) can influence the query.
Successful exploitation could allow:
- Disclosure of arbitrary database contents, including credentials and session tokens.
- Replay of disclosed session tokens to gain global administrator access.
- Subsequent actions available to a global administrator, including running scripts on enrolled hosts.
This issue requires Fleet Premium with the Okta conditional access integration enabled. It does not affect instances where Okta conditional access is not configured.
Workarounds
If an immediate upgrade is not possible, disable the Okta conditional access integration until the patched version is deployed.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/fleetdm/fleet, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/fleetdm/fleet to 4.86.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-54245 is resolved across your whole dependency graph.
Workarounds
Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.
