Internal service disclosure via unchecked redirect destinations
Published Jun 30, 2026 · Updated Jun 30, 2026
SSRF in the API Request component in IBM Langflow OSS 1.0.0 through 1.9.3 allows remote authenticated users to read internal HTTP services. The APIRequestComponent.make_api_request method validates and pins only the initial URL, then passes attacker-controlled follow_redirects to an HTTP client without revalidating each redirect destination. A low-privileged flow author must enable redirect following and supply a public URL that redirects to localhost or a private address, exposing responses from reachable internal services.
