CVE-2026-12765Network attack vectorHinoki check available

Internal network access via unvalidated flow URLs

Published Sep 14, 2026 · Updated Sep 14, 2026

SSRF in IBM Langflow OSS 1.0.0 through 1.10.2 allows remote attackers to send unauthorized server-side requests to network services. Flow components accept user-supplied URL values and issue outbound HTTP requests without applying existing SSRF protection utilities. IBM labels this CVE unauthenticated, while the shared component narrative names authenticated flow endpoints; successful requests can reach internal services and disclose responses.
