## Machine-written summary

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

> Two XWiki Maven packages, xwiki-platform-oldcore and xwiki-platform-legacy-oldcore, are affected in versions from 9.8-rc-1 up to 16.4.7, from 16.5.0-rc-1 up to 16.10.5, and from 17.0.0-rc-1 up to 17.2.0-rc-1. An attacker with edit rights on a wiki page can create a class that exposes password properties, such as users' password hashes, and any user with an account can then read them under a standard rights setup. Upgrade to 16.4.7, 16.10.5, or 17.2.0-rc-1 as appropriate; no workaround is listed.

## 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-r38m-cgpg-qj69>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
