Description
RAGFlow is an open-source RAG (Retrieval-Augmented Generation) engine. In versions 0.24.0 and prior, a Server-Side Template Injection (SSTI) vulnerability exists in RAGFlow's Agent workflow Text Processing (StringTransform) and Message components. These components use Python's jinja2.Template (unsandboxed) to render user-supplied templates, allowing any authenticated user to execute arbitrary operating system commands on the server. At time of publication, there are no publicly available patches.
Analysis
Server-Side Template Injection in RAGFlow 0.24.0 and earlier allows authenticated users to execute arbitrary OS commands via unsandboxed Jinja2 template rendering in Agent workflow components. The vulnerability affects the Text Processing (StringTransform) and Message components, where user-supplied templates are processed without sandboxing. …

Remediation
Within 24 hours: Identify all RAGFlow 0.24.0 and earlier deployments and document current user access lists for agent workflow components. Within 7 days: Restrict agent workflow creation and editing permissions to only essential personnel; disable or isolate RAGFlow instances that process sensitive data until patching is available. …
