## Affected packages

- `io.crate:crate` (Maven): affected `<5.2.11 || >=5.3.0, <5.3.8 || >=5.4.0, <5.4.7 || >=5.5.0, <5.5.2`; fixed in `5.2.11`, `5.3.8`, `5.4.7`, `5.5.2`

## Machine-written summary

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

> CrateDB (io.crate:crate) versions before 5.2.11, from 5.3.0 before 5.3.8, from 5.4.0 before 5.4.7, and from 5.5.0 before 5.5.2 are affected. When password authentication is configured with local addresses allowed, a remote attacker can bypass authentication in the Admin UI by sending a crafted X-Real-IP request header and gain access as the default user. Upgrade to 5.2.11, 5.3.8, 5.4.7, or 5.5.2 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-7mgx-gvjw-m3w3>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
