## Affected packages

- `github.com/sipeed/picoclaw` (Go): affected `<=0.2.4`; no fixed version yet

## Machine-written summary

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

> PicoClaw versions up to and including 0.2.4 are affected by a command injection flaw in the Web Launcher Management Plane, specifically the /api/gateway/restart endpoint. The source does not describe the exact manipulation, but says it can be triggered remotely, which suggests an attacker with network access to the launcher could run commands. No fix is listed, and the project has not yet responded to the report, so no patched version is available.

## 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-6r3x-h84w-fhxx>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
