CVE-2026-47412

PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an authorization bypass enabling destructive action. The DELETE /workspaces/{workspace_id} endpoint is gated only by require_workspace_member(workspace_id) (default min_role="member"). Any member of the workspace can issue a single DELETE to wipe the entire workspace, including every project, issue, comment, agent, label, and member record (cascading via the foreign-key relationships). There is no owner-role gate, no confirmation token, no soft-delete window, no recovery path. PraisonAI Platform version 0.1.4 patches the issue.

Summary

Type: Authorization bypass enabling destructive action. The DELETE /workspaces/{workspace_id} endpoint is gated only by require_workspace_member(workspace_id) (default min_role="member"). Any member of the workspace can issue a single DELETE to wipe the entire workspace, including every project, issue, comment, agent, label, and member record (cascading via the foreign-key relationships). There is no owner-role gate, no confirmation token, no soft-delete window, no recovery path. File: src/praisonai-platform/praisonai_platform/api/routes/workspaces.py, lines 77-86; services/workspace_service.py's delete() method. Root cause: the route uses Depends(require_workspace_member) which defaults to min_role="member" and is never overridden. The service method WorkspaceService.delete(workspace_id) performs the destructive operation without any caller-permission verification. The role hierarchy (MemberService.has_role, member_service.py:80-96) is implemented but unused for this endpoint.

Affected Code

@router.delete("/{workspace_id}", status_code=status.HTTP_204_NO_CONTENT)
async def delete_workspace(
    workspace_id: str,
    user: AuthIdentity = Depends(require_workspace_member),         # <-- BUG: defaults to min_role="member"
    session: AsyncSession = Depends(get_db),
):
    ws_svc = WorkspaceService(session)
    deleted = await ws_svc.delete(workspace_id)                     # <-- destructive, no role check
    if not deleted:
        raise HTTPException(status_code=404, detail="Workspace not found")

Why it's wrong: workspace deletion is the most destructive single action in this product — it wipes every member, project, issue, comment, agent, and label belonging to the tenant. The standard convention is to gate this on owner role, ideally with a confirmation parameter (typed workspace name) and a recovery window. This endpoint does none of that. The require_workspace_member(min_role) parameter exists precisely for this kind of tightening but is never invoked with anything other than the default.

Exploit Chain

1. Attacker is a member of workspace W (joined via invite, signup default, or any other route into membership). State: attacker holds JWT with Member(workspace_id=W, user_id=attacker, role="member").
2. Attacker sends DELETE /workspaces/W with Authorization: Bearer <attacker_jwt>. State: control flow enters delete_workspace.
3. require_workspace_member(W, attacker) passes (attacker is a member, default min_role="member" satisfied). WorkspaceService.delete(W) removes the workspace row; SQLAlchemy cascade rules drop every related row (members, projects, issues, comments, agents, labels). State: workspace W no longer exists.
4. Final state: a low-privilege member has wiped the workspace. The legitimate owner has no recovery: no soft-delete, no audit-trail event for the deletion (the Activity log row would have been deleted too as part of the cascade). The same primitive at scale (script that DELETEs every workspace_id the attacker can enumerate) becomes a multi-tenant griefing tool.

Security Impact

Severity: sec-high. CVSS 8.1: network attack, low complexity, low privileges, no user interaction, scope unchanged, no confidentiality (just destruction), high integrity (every workspace child row wiped), high availability (workspace gone for legitimate owner). Attacker capability: with one workspace-member token plus one DELETE request, the attacker irreversibly deletes the workspace and every child resource. The deletion is silent and immediate. Preconditions: praisonai-platform is deployed multi-tenant; the attacker has any membership token in the target workspace. Differential: source-inspection-verified. The asymmetry between require_workspace_member's clearly-tunable min_role parameter and this endpoint's use of…
