Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Plane 是一款开源的项目管理工具。在版本 1.4.0 之前，Plane 的项目更新端点仅根据请求 URL 中的工作区 slug（workspace slug）对调用者进行授权，但通过全局 UUID 加载目标项目，而未将其与该工作区绑定。如果已知受害者项目的 UUID，某一工作区的管理员即可修改另一工作区中的项目。此漏洞破坏了租户隔离机制，导致未经授权的对项目元数据和配置进行跨工作区修改。该问题已在版本 1.4.0 中得到修复。

Vulnerability Title
Plane: Cross-Workspace Project Modification via Unscoped Project Lookup
Source: CVE Program / CVE List V5
Vulnerability Description
Plane is an open-source project management tool. Prior to 1.4.0, Plane's project update endpoint authorizes the caller against the workspace slug in the request URL but loads the target project globally by UUID without binding it to that workspace. An administrator of one workspace can modify a project in another workspace when the victim project UUID is known. This violates tenant isolation and permits unauthorized cross-workspace changes to project metadata and configuration. This issue is fixed in 1.4.0.
