CVE-2026-47409: MervinPraison PraisonAI Platform authorization bypass in member removal

CVE-2026-47409 · Severity: high · CVSS 8.1 · Published 2026-07-21

PraisonAI Platform, a system for managing multi-agent AI teams, contains a security flaw that allows any workspace member to lock out other users. Because the system fails to verify if a user has administrative rights before removing members, a low-privileged user can delete the workspace owner's access. This results in a permanent loss of control for the legitimate owner and disrupts business operations within that workspace.

Technologies: praisonai-platform (PyPI). Vendors: PyPI.

Technical details

An authorization bypass exists in the `DELETE /workspaces/{workspace_id}/members/{user_id}` endpoint of PraisonAI Platform. The endpoint is protected by the `require_workspace_member` dependency, which defaults to a minimum role of 'member', but it lacks additional logic to verify the caller's role relative to the target or to prevent the removal of the final workspace owner. An authenticated attacker with 'member' privileges can obtain the owner's `user_id` (via the list members endpoint) and issue a DELETE request to revoke the owner's access. This leads to a permanent lockout of the legitimate owner. The issue is addressed in version 0.1.4 by enforcing stricter role checks and workspace scoping.
