Published by the GitHub Advisory Database at 25 Sept 2023, 21:30 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `org.codehaus.plexus:plexus-utils` (Maven): affected `<3.0.24`; fixed in `3.0.24`

## Machine-written summary

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

> The plexus-utils package, versions before 3.0.24, is vulnerable to XML injection. The XmlWriterUtil writeComment method does not sanitize comment text for the "-->" sequence, so text in a comment can be read as XML markup. The source does not describe what an attacker must control or what the impact would be in practice. Upgrade plexus-utils to version 3.0.24 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-jcwr-x25h-x5fh>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
