CVE-2026-47409

praisonai-platform: Any workspace member can remove any other member (including the owner) via DELETE /workspaces/{id}/members/{user_id}

Published Jul 21, 2026 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed
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.
