## Machine-written summary

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

> Apache Camel's camel-coap, camel-google-pubsub, camel-jms and camel-sjms modules are affected from 3.0.0 before 4.14.6, from 4.15.0 before 4.18.2, and from 4.19.0 before 4.20.0. An attacker with producer access to a JMS or equivalent broker consumed by a Camel route can inject case-variant internal headers, which can lead to remote code execution or arbitrary file write in routes that forward messages to header-driven components. Upgrade to 4.14.6, 4.18.2, or 4.20.0 depending on your release stream.

Written 2 Nov 2026.

## 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-jg2m-9x48-3gvj>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
