CVE-2026-7754Network attack vector

Authenticated internal data access via disabled SSRF protection

Published Jul 17, 2026 · Updated Jul 17, 2026

SSRF in IBM Langflow OSS 1.0.0 through 1.10.0 allows remote authenticated users to read internal resources via crafted URLs. The ssrf_protection_enabled setting defaults to false, causing the server to bypass URL validation and fetch arbitrary destinations. Standard authenticated access is required; responses can expose cloud metadata, Docker APIs, and services reachable from the Langflow host.
