Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Flowise packages flowise and flowise-components before 3.1.3 are affected. The CSV Agent and Airtable Agent nodes filter LLM-generated Python with a regex blocklist, which the report says can be bypassed through prompt injection sent to the unauthenticated prediction API, letting an attacker send loaded data to an external server and reach internal services. Upgrade to flowise or flowise-components 3.1.3.
