## Affected packages

- `utcp-websocket` (PyPI): affected `<1.1.1`; fixed in `1.1.1`

## Machine-written summary

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

> Packages utcp-gql and utcp-websocket before 1.1.1 are affected by server-side request forgery. The GraphQL plugin uses a prefix URL check that hostnames such as 127.0.0.1.attacker.example can pass, and the WebSocket plugin performs no URL validation. An attacker who can get a client to register a malicious manual can direct requests to internal services and send configured API keys or tokens to an attacker-chosen host. Upgrade both packages to 1.1.1.

## 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-ppx3-28rw-8fpf>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
