CVE-2026-6587Public exploitNetwork attack vector

Authenticated SSRF via unrestricted retrieved context URLs

Published Apr 20, 2026 · Updated Apr 20, 2026

Server-side request forgery in Vibrant Labs Ragas 0.2.3 through 0.4.3 allows remote authenticated users to reach internal resources. In the Collections Module, _try_process_url passes each retrieved_contexts URL to requests.get after checking only for HTTP or HTTPS, without rejecting loopback, private, or link-local destinations. Exploitation requires an application to accept attacker-controlled evaluation contexts and can expose internal services or cloud metadata through the application's processing path.
