## Affected packages

- `filippo.io/age` (Go): affected `<1.2.1`; fixed in `1.2.1`

## Machine-written summary

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

> The Go package filippo.io/age versions before 1.2.1 are vulnerable. A plugin name containing a path separator, supplied through an attacker-controlled recipient or identity string, can cause an arbitrary binary to be executed; on UNIX systems this also requires a directory matching the age plugin temporary path pattern to exist. Upgrade to version 1.2.1 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-32gq-x56h-299c>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
