Name of the Vulnerable Software and Affected Versions Fleet Server (affected versions not specified)
Description Incorrect authorization in Fleet Server allows an authenticated agent to interfere with active multi-part data upload sessions belonging to other enrolled agents. This occurs because the server fails to correctly verify session ownership during these operations, which can lead to a denial of service for agent upload operations through privilege abuse.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
