Path Traversal in Flowise Vector Store Implementations
Flowise
Flowise contains a path traversal vulnerability in Faiss and SimpleStore vector store implementations accepting unsanitized basePath parameters. Authenticated attackers with API tokens can write vector store data to arbitrary filesystem locations.
disclosed CVENo confirmed exploitation, so this record is tracked as a disclosed vulnerability and not counted as an incident. It moves into the counts if CISA or the vendor confirms exploitation. Why
