Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
Flowise through 3.1.4 contains missing route-level RBAC checks on chat message endpoints that allow low-privileged API keys to read and delete chat history. Attackers with valid but low-privileged API keys can access GET and DELETE chat message routes without required flow permissions to read chat histories, prompts, model responses, and delete messages.
