## Affected packages

- `librenms/librenms` (Packagist): affected `<25.7.0`; fixed in `25.7.0`

## Machine-written summary

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

> LibreNMS version 25.6.0 is affected by a flaw in the ajax_form.php endpoint, where the POST parameter "type" is used to include files without validation. An authenticated attacker who can place a file in the included forms directory, such as through a symlink, could achieve remote code execution as the librenms user. The source gives few details on how such a file would be staged. Upgrade to LibreNMS 25.7.0 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-gq96-8w38-hhj2>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
