Unauthenticated internal data disclosure via unchecked URL fetch
Published Apr 7, 2026 · Updated Apr 7, 2026
SSRF in the superbooga and superboogav2 RAG extensions in oobabooga text-generation-webui before 4.3 allows remote attackers to read internal data. The download_single functions pass URLs from the Gradio Input URLs textbox directly to requests.get without scheme, hostname, IP-address, or redirect validation. When either extension is enabled, unauthenticated network access is enough to retrieve cloud metadata or internal-service content and expose it through later RAG responses.
