## Affected packages

- `github.com/gravitl/netmaker` (Go): affected `<0.8.5 || >=0.9.0, <0.9.4`; fixed in `0.8.5`, `0.9.4`

## Machine-written summary

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

> Netmaker versions before 0.8.5 and from 0.9.0 before 0.9.4 contain a hard-coded cryptographic key in the server component. A remote attacker who knows the address and username of an admin can exploit this to run admin commands on the server; clients are not affected. Upgrade to Netmaker 0.8.5, 0.9.4, or 0.10.0 or later.

## 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-86f3-hf24-76q4>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
