Payload 是一款免费且开源的无头内容管理系统（Headless CMS）。在版本低于 3.90.0 以及低于 4.0.0-canary.34 的 canary 版本中，存在安全漏洞：如果集合（collection）或连接字段（join field）上启用了“可排序”（orderable）功能，攻击者可以向特定的更新端点提交请求，从而修改集合文档，而系统在此过程中未强制执行集合级别或字段级别的访问控制。该问题已在版本 3.90.0 和 4.0.0-canary.34 中得到修复。

Vulnerability Title
Payload: Unauthorized update to collection documents
Source: CVE Program / CVE List V5
Vulnerability Description
Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, an attacker can submit a request to a specific update endpoint that modifies collection documents without enforcing collection or field-level access control when orderable is enabled on a collection or join field. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
