Detailsinfo

A vulnerability, which was classified as critical, was found in Infiniflow RAGFlow up to 0.26.x. This affects the function set_api_key of the file api/apps/llm_app.py of the component Llm Api. The manipulation of the argument base_url with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

RAGFlow before 0.27.0 contains a server-side request forgery vulnerability that allows authenticated attackers to force the server to issue requests to arbitrary internal or external endpoints by supplying an unvalidated base_url to the POST /v1/llm/set_api_key endpoint handled by set_api_key() in api/apps/llm_app.py. Attackers can exploit this flaw to probe shared-network services such as MySQL, Elasticsearch, Redis, MinIO, the Infinity vector database, and cloud metadata endpoints, with raw upstream exception text returned in the response leaking internal service details, open ports, and configuration fingerprints.
