RAGFlow is designed as an open-source engine for Retrieval-Augmented Generation, which is commonly deployed as a web-based application or API service. Because such systems are frequently exposed to the internet to provide external accessibility for LLM-integrated workflows and user interfaces, the vulnerable component is likely to be reachable from the internet in standard deployments.

Horizon Alert

Summary of the vulnerability and why it matters

RAGFlow, an open-source engine for Retrieval-Augmented Generation, contains a vulnerability in its prompt generator. This flaw allows an authenticated user to execute unauthorized operating system commands on the server. The impact could affect system integrity and data confidentiality.

  • Prompt generation flaw
  • Arbitrary OS command execution
  • Business risk and data compromise

Attack Path

How an attacker could exploit the issue

A vulnerability in RAGFlow's prompt generator could allow an authenticated user to execute arbitrary operating system commands. This occurs when a user creates a specific workflow that combines a search component with a language model. The system processes this workflow using a Jinja2 template, which, when malformed, allows for the injection of commands. Successful exploitation would grant the attacker control over the server.

  • Exposed to the network.
  • Authenticated user registers.
  • Trigger workflow; execute OS commands.

Frequently asked questions

What is RAGFlow and its purpose in AI systems?

RAGFlow is an open-source engine that enhances Retrieval-Augmented Generation (RAG) systems. It integrates external data sources with large language models, enabling more precise and contextually relevant responses.

What weakness class characterizes CVE-2026-45312 in RAGFlow?

CVE-2026-45312 is classified as a command injection vulnerability (CWE-1336). This critical flaw permits an authenticated user to execute unintended operating system commands on the server hosting RAGFlow.

How can an authenticated user trigger the RAGFlow command injection vulnerability?

An authenticated user can exploit this vulnerability by creating a specific workflow. This workflow involves a search component, like DuckDuckGo, chained with a language model. The system's processing of this workflow through a Jinja2 template facilitates the command injection.

What is the significance of the Halo Surface Signal assessment for CVE-2026-45312?

The Halo Surface Signal indicates a 'Likely' chance of this vulnerability being exploited. This is because RAGFlow, often deployed as a web application or API, is typically exposed to the internet, making the vulnerable component accessible.

What steps should be taken to address the RAGFlow command injection vulnerability?

Organizations should identify RAGFlow assets exposed to the network, isolate affected systems or restrict access, apply vendor-provided fixes, and monitor for suspicious activity to mitigate the risk of unauthorized access and data compromise.
