## Affected packages

- `misp-modules` (PyPI): affected `<3.0.8`; fixed in `3.0.8`

## Machine-written summary

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

> misp-modules, versions up to and including 3.0.7, has unsafe remote resource fetching in its expansion modules. The html_to_markdown module accepts arbitrary HTTP(S) URLs without sufficient validation, enabling Server-Side Request Forgery against loopback, private, or link-local network resources, and the qrcode module disables TLS certificate verification when fetching remote images, allowing possible man-in-the-middle interception. No fixed version is listed.

## 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-fhq3-2gf3-8f3j>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
