CVE-2026-47409 is an authorization bypass vulnerability in PraisonAI Platform, the platform layer for the PraisonAI multi-agent teams system. In versions prior to 0.1.4, the workspace member removal endpoint only verifies that the caller is a member of the workspace. The vulnerable logic on the DELETE member endpoint does not enforce caller-role authorization, does not validate the target member's role, and does not prevent removal of the last remaining owner. As a result, any authenticated workspace member can issue a deletion request against another workspace member record, including the workspace owner, and remove that user from the workspace. This can lead to owner lockout and unauthorized modification of workspace membership and administrative control.
