CVE-2026-26061 Â (opens in a new tab)How to fix?
Upgrade github.com/fleetdm/fleet/server/service to version 4.81.0 or higher.
Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of request body size limits in unauthenticated HTTP endpoints. An attacker can exhaust server memory and cause process restarts by sending large or repeated HTTP payloads.
Workaround
This vulnerability can be mitigated by applying request body size limits at a reverse proxy or load balancer, restricting network access to endpoints to known IP ranges, and monitoring memory usage and restart frequency for abnormal patterns.
