## 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.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-j8f7-x8jm-wmm4>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
