HIGH

PraisonAI Platform missing role checks let any workspace member become owner and take over workspace membership

Title source: cna
STIX 2.1

Description

PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have a broken workspace authorization check that allows any authenticated low-privilege workspace member to escalate their own role to `owner`. The issue is caused by privileged workspace-management routes using the shared dependency `require_workspace_member(...)` without requiring `admin` or `owner`. The dependency defaults to `min_role="member"`, so routes that should be administrative are accessible to ordinary workspace members. As a result, a normal workspace member can promote their own account from `member` to `owner`; add arbitrary users as `owner` or `admin`; change other members' roles; remove legitimate owners or members; take over workspace membership completely; and/or perform destructive workspace operations after escalation. This is a broken access control / vertical privilege escalation vulnerability. PraisonAI Platform version 0.1.4 patches the issue.
