A fix is available — apply it.

Flowise before 3.1.0 contains a path traversal vulnerability in Faiss and SimpleStore vector store implementations that accept unsanitized basePath parameters from authenticated users. Attackers with valid API tokens can write vector store data to arbitrary filesystem locations, potentially enabling code execution or data exfiltration.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
