## Affected packages

- `torrentpier/torrentpier` (Packagist): affected `<2.4.4`; fixed in `2.4.4`

## Machine-written summary

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

> The torrentpier/torrentpier PHP package before 2.4.4 is affected by PHP object injection, where unsafe handling of serialized data could let an attacker modify serialized objects. The source gives few details on how an attacker would reach the vulnerable code, but it states that successful exploitation could lead to code execution or arbitrary file reads. Upgrade to version 2.4.4 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-h29g-c9cx-c73q>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
