Title
Flowise before 3.1.4 Cross-Tenant Organization Admin Takeover
Summary
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.

Mitigation MIT-1
Architecture and Design Operation

Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.

Mitigation MIT-17
Architecture and Design Operation

Strategy: Environment Hardening

Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.

No CAPEC attack patterns related to this CWE.
