Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Langflow (PyPI packages langflow, langflow-base, lfx and lfx-docling) before 1.10.3 lets built-in components such as RSS Reader, SearXNG, Web Search, Home Assistant, Glean and Docling Serve send server-side requests to arbitrary URLs without SSRF protection. An authenticated user who can build or run flows can reach loopback, private-network and cloud metadata addresses and may read responses through the component output. Upgrade to langflow 1.10.3, langflow-base 0.10.3, lfx 1.10.3 or lfx-docling 0.1.2, and do not disable SSRF protection.
