## Machine-written summary

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

> Maven package io.openremote:openremote-agent, versions before 1.24.2, is vulnerable to XML external entity (XXE) injection in the KNX asset import handler (KNXProtocol). The fix for CVE-2026-40882 covered only the Velbus import handler. An authenticated user who uploads a crafted ETS project ZIP file can read arbitrary files readable by the server process and possibly make server-side requests. Upgrade to version 1.24.2 or later. No workaround is given.

## 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-7v6w-c3f4-9wpq>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
