Security Bulletin: Langflow is affected by improper authorization due to missing access control on the voice-mode WebSocket endpoint

Summary Langflow provides a voice-mode feature through a WebSocket API endpoint that accepts a flow identifier as a URL path parameter and uses it to retrieve the target flow description and persist conversation messages against that flow. The endpoint authenticates the connecting user's identity...

Security Bulletin: Langflow OSS is affected by arbitrary file read due to path traversal vulnerabilities in file and knowledge base components

Summary Langflow uses filesystem path construction as part of several components and API endpoints, including the Directory component, the Knowledge Base connector ingestion endpoint, and the Knowledge Base flow component. In the Directory component, user-supplied path values are not validated...
