## Affected packages

- `langchain-nvidia-ai-endpoints` (PyPI): affected `<1.4.2`; fixed in `1.4.2`

## Machine-written summary

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

> Versions of langchain-nvidia-ai-endpoints before 1.4.2 accepted local filesystem paths as image inputs for VLM requests in ChatNVIDIA and NVIDIARerank. An attacker who can control image URLs or document image metadata in an application using these inputs could read files the application process can access and send them to the model endpoint. Upgrade to 1.4.2 or later, which rejects raw local paths; until then, reject local paths in user-supplied image inputs.

## 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-g28h-2cmm-rj9x>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
