Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Fleet 是一个基于 osquery 构建的开源设备管理平台。在 4.85.0 之前的版本中，全局策略读取端点（GET /api/latest/fleet/policies/{policy_id}）未能验证所请求策略的团队归属，这使得任何仅拥有单个团队观察者（observer）级别权限的已认证用户，能够读取其他团队策略的完整详情，从而绕过 Fleet 的团队隔离模型。具体而言，处理程序使用一个 TeamID 为 nil 的空策略对象进行授权检查，而授权规则允许拥有任意团队角色的用户通过该检查；随后，系统按 ID

Vulnerability Title
Fleet: Cross-Team Policy Data Exposure via Global Policy Read Endpoint
Source: CVE Program / CVE List V5
Vulnerability Description
Fleet is an open-source device management platform built on osquery. In versions prior to 4.85.0, the global policy read endpoint (GET /api/latest/fleet/policies/{policy_id}) fails to verify team ownership of the requested policy, allowing an authenticated user with observer-level access on any single team to read the full details of policies belonging to any other team and bypass Fleet's team isolation model. The handler authorizes the request against an empty policy object whose TeamID is nil, which an authorization rule permits for any user holding a role on any team, and then fetches the policy by ID with no team filter and returns it without any post-fetch scope check. Because policy IDs are sequential integers, an attacker can enumerate them to read other teams' policy SQL queries, host pass and fail counts, and associated software-installer and script metadata, exposing security-monitoring strategies and compliance posture across team boundaries. This issue is fixed in version 4.85.0.
