 - Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.0, Langflow is
 vulnerable to Path Traversal in the Knowledge Bases API (POST /api/v1/knowledge_bases). This occurs
 because user-supplied knowledge base names are used directly to create file paths without proper
 sanitization or containment checks. An authenticated attacker can exploit this flaw to create directories
 and write files anywhere on the server's filesystem. This vulnerability is fixed in 1.9.0.
