GHSA-hp26-q66v-q2w7: FlowiseAI has Mass Assignment in Assistant Update Endpoint that Allows Cross-Workspace Resource Reassignment

Summary

An authenticated user can exploit a Mass Assignment flaw in the PUT /api/v1/assistants/{assistantId} endpoint of FlowiseAI. The server does not restrict which properties the client may modify, so requests can change server-controlled fields such as workspaceId, createdDate and updatedDate. This allows an attacker to reassign assistants to arbitrary workspaces, breaking tenant isolation in multi-workspace deployments.

Mitigation

The source does not state a fix yet. Check the original advisory for updates.
