## What is CVE-2026-47413?

CVE-2026-47413 is a critical vulnerability in MervinPraison praisonai-platform, published on 21 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have aprivilege escalation / cross-tenant member injection. The `POST /workspaces/{workspace_id}/members` endpoint is gated only by `require_workspace_member(workspace_id)` (default `min_role="member"`) and forwards the request body's `user_id` and `role` straight into `MemberService.add(workspace_id, user_id, role)`, which has no caller-permission check. A user with the lowest workspace privilege can add any user (including a new attacker-controlled second account, or an existing account they want to grief) as owner of the workspace. PraisonAI Platform version 0.1.4 patches the issue.

Weakness: CWE-862 (Missing Authorization), CWE-269 (Improper Privilege Management)
