Flowise: Path Traversal in Vector Store basePath

Summary The Faiss and SimpleStore LlamaIndex vector store implementations accept a basePath parameter from user-controlled input and pass it directly to filesystem write operations without any sanitization. An authenticated attacker can exploit this to write vector store data to arbitrary locatio...
