CVE-2026-75898
HighCVSS 8.5Summary
RAGFlow before version 0.26.3 has a server-side request forgery vulnerability in the agent workflow Invoke component. The component builds an outbound request URL from canvas configuration and template variables and passes it to requests.get/post/put without safety validation, allowing access to internal network resources.
Risk Assessment
An attacker can direct the server to fetch data from internal addresses, including cloud instance metadata, potentially leading to disclosure of sensitive information or attacks on co-located services.
Recommendation
Upgrade RAGFlow to version 0.26.3 or later, which includes the fix.
Original NVD description (English source)
RAGFlow before 0.26.3 contains a server-side request forgery vulnerability in the agent workflow "Invoke" component (agent/component/invoke.py). The component builds an outbound request URL from canvas configuration and runtime template variables and passes it to requests.get, requests.post, or requests.put without calling the shared assert_url_is_safe validator or pinning the resolved address, unlike the crawler, SearXNG, file-upload, and RSS fetch paths. A user who can create or trigger an agent can direct the server to fetch loopback, link-local, and RFC 1918 destinations, including cloud instance metadata endpoints and services co-located on the deployment network, and the response body is returned as the component output. Where an agent is configured to interpolate the chat query into the Invoke URL, the destination is chosen by whoever can send that query.
