CWE-639

Description

Authorization Bypass Through User-Controlled Key (CWE-639) in Fleet Server can lead to information disclosure via Manipulating User-Controlled Variables (CAPEC-77). The authorization decision for artifact downloads relied on a client-supplied value that was persisted without being validated against the server-side record of the requesting agent's assignment. An authenticated party in possession of a valid enrolled agent credential could therefore retrieve a policy the agent is not assigned to.

Affected configurations

• elastic fleet server (>= 8.3.0 < 8.19.20) • elastic fleet server (>= 9.0.0 < 9.4.5) • elastic fleet server 9.5.0
