Infiniflow RAGFlow Trace Mindmap Access Control Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-51893

RAGFlow is designed as a web-based document processing and RAG application that is commonly deployed as an internet-facing service to provide web UI or API endpoints for end users, making its internal paths and functional components, such as trace_mindmap, typically reachable over the network in standard deployments.

Horizon Alert

Summary of the vulnerability and why it matters

A vulnerability has been identified in a technology used for processing and retrieving information, specifically impacting how access controls are managed. This weakness could allow unauthorized access to data within the system. The primary concern is to determine if this technology is in use and if it is exposed to potential threats.

Unrestricted access to sensitive information.
Confirm relevance and exposure.
Understand potential data access risks.

Attack Path

How an attacker could exploit the issue

An attacker could reach a vulnerable component within RAGFlow by exploiting an externally accessible path that accepts user-provided identifiers. This path leads to a data-access operation that lacks proper authorization checks for ownership or membership, potentially allowing unauthorized access to sensitive information or the ability to manipulate data.

Entry: No authentication required.
Trigger: Call trace_mindmap with a crafted identifier.
Risk: Unauthorized data access and modification.

Live Threat

Current exploitation, exposure, and threat context

The infiniflow ragflow trace_mindmap feature could allow unauthorized access to sensitive system data when an attacker provides a specific object or tenant identifier. This occurs because the system may not adequately verify ownership or membership before performing data operations.

System data and tenant information.
Exploiting insecure access control.
Unauthorized data access and modification.

Operational Fix

Recommended remediation, mitigation, and detection steps

The RAGFlow application, commonly deployed as an internet-facing service, likely requires action from platform or application owners responsible for its infrastructure and access controls. The immediate priority is to identify all instances of RAGFlow, confirm their reachability and business criticality, and then ascertain the accountable owner before planning remediation based on assessed risk.

Platform or application owners should lead.
Verify external reachability and business criticality.
Plan remediation based on risk assessment.

Frequently asked questions

What is Infiniflow RAGFlow?

RAGFlow is an open-source Retrieval-Augmented Generation (RAG) engine designed to help users process documents and interact with them via an intelligent interface. It acts as a central hub where organizations store, index, and query structured and unstructured data, providing both a web UI and API endpoints to facilitate these data-driven workflows.

What does Incorrect Access Control mean for CVE-2026-51893?

This vulnerability, classified as Improper Access Control (CWE-284), means the system fails to verify who you are or what you are allowed to see before granting access to data. In the context of CVE-2026-51893, the software neglects to check if a specific user belongs to the tenant or workspace associated with the requested object, allowing unauthorized requests to bypass security boundaries.

How is the trace_mindmap feature triggered?

The flaw is triggered when an attacker accesses the trace_mindmap path and provides a specific object or tenant identifier. The vulnerability does not require any authentication or previous system knowledge; if the path is reachable, simply submitting a target identifier is sufficient to initiate the unauthorized data operation.

How do I know if this CVE is relevant to my environment?

Halo Surface Signal indicates that RAGFlow is typically deployed as an internet-facing service to support end-user access. Because the service is designed for external network connectivity, any instance of RAGFlow exposed to the internet is likely reachable, making it a priority to investigate if your specific setup permits access to the affected path.

What should I do if I am running RAGFlow?

First, conduct an inventory to locate every instance of RAGFlow within your infrastructure. Once identified, determine if these instances are accessible from the internet or restricted to internal networks. After assessing your exposure and the business importance of the data stored within the application, coordinate with your technical team to address the security gap.
