CVE-2026-22808 [MEDIUM] CWE-79 CVE-2026-22808: fleetdm/fleet is open source device management software. Prior to versions 4.78.2, 4.77.1, 4.76.2, 4 fleetdm/fleet is open source device management software. Prior to versions 4.78.2, 4.77.1, 4.76.2, 4.75.2, and 4.53.3, if Windows MDM is enabled, an unauthenticated attacker can exploit this XSS vulnerability to steal a Fleet administrator's authentication token (FLEET::auth_token) from localStorage. This could allow unauthorized access to Fleet, inc

CVE-2026-23999 [MEDIUM] CWE-330 CVE-2026-23999: Fleet is open source device management software. In versions prior to 4.80.1, Fleet generated device Fleet is open source device management software. In versions prior to 4.80.1, Fleet generated device lock and wipe PINs using a predictable algorithm based solely on the current Unix timestamp. Because no secret key or additional entropy was used, the resulting PIN could potentially be derived if the approximate time the device was locked is known.

CVE-2021-21296 [LOW] CWE-400 CVE-2021-21296: Fleet is an open source osquery manager. In Fleet before version 3.7.0 a malicious actor with a vali Fleet is an open source osquery manager. In Fleet before version 3.7.0 a malicious actor with a valid node key can send a badly formatted request that causes the Fleet server to exit, resulting in denial of service. This is possible only while a live query is currently ongoing. We believe the impact of this vulnerability to be low given the requirement
