Description
Flowise before 3.1.4 fails to scope enterprise organization and workspace membership APIs to the caller's tenant, allowing authenticated users to supply arbitrary organization IDs. Attackers can add themselves as organization owners, create workspaces, and gain administrative access to victim organizations by exploiting insufficient tenant isolation in the organizationuser and workspace endpoints.
