## Affected packages

- `ms-swift` (PyPI): affected `<=4.2.0`; no fixed version yet

## Machine-written summary

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

> The ms-swift package is vulnerable in versions up to and including 4.2.0. A local attacker can exploit a weak hash in the image cache key handling, which is difficult to carry out, and a public exploit exists. The source gives few details on the impact. 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-prfw-69r3-wqxf>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
