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.
