Flowise: Unauthenticated Property Injection into Flow Execution Context via Ungated `overrideConfig` Spread in Prediction API

Summary The POST /api/v1/prediction/:id endpoint — which is unauthenticated whitelisted in WHITELISTURLS — accepts an overrideConfig object in the request body. This object is unconditionally spread into the internal flowConfig and flowData objects at two locations in the codebase without checkin...

Flowise before 3.1.3 is vulnerable: unauthenticated POST /api/v1/prediction/:id accepts an overrideConfig object that is blindly spread into internal flowConfig and flowData without validating apiOverrideStatus. This enables attackers to inject arbitrary properties into the flow execution context...
