CVE-2026-47409 Details
Description
PraisonAI Platform is the platform layer for the PraisonAI multi-agent teams system. Versions prior to 0.1.4 have an authorization bypass enabling owner lockout. The `DELETE /workspaces/{workspace_id}/members/{user_id}` endpoint is gated only by `require_workspace_member(workspace_id)` (default `min_role="member"`). Any member can remove any other member, including the workspace owner, using a single DELETE. There is no caller-role check, no target-role check, no "cannot remove last owner" guard. PraisonAI Platform version 0.1.4 patches the issue.
An authorization bypass vulnerability has been identified in the PraisonAI Platform, specifically in versions prior to 0.1.4. This vulnerability allows any workspace member to remove other members, including the workspace owner, through the DELETE /workspaces/{workspace_id}/members/{user_id} endpoint. The endpoint only requires the user to be a workspace member, without checking roles or preventing the removal of the last owner. As a result, a member can effectively lock the owner out of the workspace.
Users can update to PraisonAI Platform version 0.1.4 or later, where this vulnerability has been patched.
