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之前版本存在授权问题漏洞，该漏洞源于不安全的直接对象引用，依赖端点仅通过require_workspace_member(workspace_id)进行访问控制，未验证URL或请求体中提供的issue_id和dependency_id是否属于已检查成员身份的工作区，可能导致攻击者在数据库中任意两个问题之间创建“blocks”或“related”链接。

Vulnerability Title
praisonai-platform: Dependency endpoints accept any issue_id and dep_id without workspace ownership check, cross-workspace issue linking + read + delete IDOR
Source: CVE Program / CVE List V5
Vulnerability Description
PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an Insecure Direct Object Reference. The dependency endpoints (`POST/GET /workspaces/{workspace_id}/issues/{issue_id}/dependencies` and `DELETE .../dependencies/{dep_id}`) gate access on `require_workspace_member(workspace_id)` only, then dispatch to `DependencyService` calls that take URL/body-supplied issue and dependency IDs without verifying any of them belong to the membership-checked workspace. Most damaging: `create_dependency` accepts `body.depends_on_issue_id` from the request body — that ID is checked against nothing — letting an attacker create a "blocks" or "related" link between any two issues anywhere in the database. PraisonAI Platform version 0.1.4 patches the issue.
