CVE-2026-47407— PraisonAI Platform has a cross-workspace IDOR + member-role privilege escalation

Quick assessment

Affected
MervinPraison praisonai-platform
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.

MervinPraison PraisonAI是MervinPraison个人开发者的 MervinPraison PraisonAI 0.1.4之前版本存在安全漏洞，该漏洞源于对workspace_id的授权检查不充分，用户可以通过在URL前缀中使用自己的工作空间并在路径中使用其他工作空间的资源ID来访问、修改或删除跨租户资源；此外，成员管理路由存在权限提升漏洞，任何基础成员可以提升自己为管理员或所有者、降级或移除其他成员以及删除工作空间。

Vulnerability Title
PraisonAI Platform has a cross-workspace IDOR + member-role privilege escalation
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Prior to version 0.1.4, the Platform server exposes resources under `/api/v1/workspaces/{workspace_id}/...` and protects them with a `require_workspace_member(workspace_id)` FastAPI dependency. The dependency only checks that the caller is a member of the workspace_id in the URL prefix. The route handlers then look up the inner resource (`agent_id`, `issue_id`, `project_id`, `label_id`, `comment_id`, `dependency_id`) by primary key alone. The resource's own `workspace_id` is never compared to the URL's `workspace_id`. A user can therefore put their own workspace in the URL prefix and any other workspace's resource ID in the path. The auth check passes, since they really are a member of the prefix workspace. The service then returns the cross-tenant resource for read, update, or delete. There is a second bug in the member-management routes (`add_member`, `update_member_role`, `remove_member`, `update_workspace`, `delete_workspace`). Each one inherits the default `min_role="member"` from `require_workspace_member`. Any basic member can therefore promote themselves to admin or owner, demote or remove other members, and delete the workspace. The role hierarchy exists in the schema but is not enforced. Registration is open at `/api/v1/auth/register` with no email verification. The default server bind is `0.0.0.0:8000` (`python -m praisonai_platform`). One curl from any unauthenticated network position is enough to bootstrap into the system. PraisonAI Platform version 0.1.4 patches the issue.
