RAGFlow: Server-Side Template Injection (SSTI) leading to Remote Code Execution (RCE) in Agent "Text Processing" Component

Assigner: GitHub_M
Reserved: 03.03.2026 Published: 03.04.2026 Updated: 03.04.2026

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.
