CVE-2026-47409 | BDVDB-2026-350464 Detail

MervinPraisonpraisonai-platform

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.

Impact#

Per CVSS v3.1: confidentiality impact none, integrity impact high, availability impact high. Attack vector: network.
