## Affected packages

- `kimai/kimai` (Packagist): affected `<2.56.0`; fixed in `2.56.0`

## Machine-written summary

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

> The kimai/kimai package before 2.56.0 lets an admin who can upload invoice or export Twig templates use the config() function to read server-wide settings, including the LDAP bind password and the SAML service provider private key. Those values can appear in rendered invoice or export output, which other users, including lower-privileged users with invoice permissions, may receive. Upgrade to kimai/kimai 2.56.0 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-vrqv-52x7-rm4v>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
