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.
PraisonAI 是一个多智能体团队协作系统。在 praisonai-platform 的 0.1.4 版本至 0.1.5 版本之前，工作区成员可以永久删除由工作区所有者或其他成员创建的任何资源，包括项目、智能体、问题、标签、问题依赖关系以及问题 - 标签附件。所有六个内容删除（DELETE）端点仅验证用户是否为工作区成员，但未执行所有权或角色权限检查。因此，单个恶意或已被攻陷的成员账户即可不可逆地清空整个工作区的所有内容。该问题已在 0.1.5 版本中修复。

Vulnerability Title
PraisonAI: Missing ownership check on DELETE endpoints allows members to delete others' content in Platform API
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI is a multi-agent teams system. From version 0.1.4 to before version 0.1.5 in praisonai-platform, a workspace member can permanently delete any resource — projects, agents, issues, labels, issue dependencies, and issue-label attachments — created by the workspace owner or other members. All six content DELETE endpoints enforce workspace membership but perform no ownership or role check. A single malicious or compromised member account can wipe an entire workspace's content irreversibly. This issue has been patched in version 0.1.5.
