## Affected packages

- `snipe/snipe-it` (Packagist): affected `<8.5.0`; fixed in `8.5.0`

## Machine-written summary

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

> Snipe-IT, the Packagist package snipe/snipe-it before 8.5.0, has a directory traversal flaw in the displaySig action of ActionlogController. The filename from the HTTP route is joined into a file path without sanitization. An authenticated attacker can use this to read arbitrary files that the web server process can access. The fix is to upgrade snipe/snipe-it to 8.5.0 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-c6f4-wj38-m3g3>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
