## Affected packages

- `org.xwiki.platform:xwiki-platform-livetable-ui` (Maven): affected `>=6.2.1, <16.10.17 || >=17.0.0-rc-1, <17.4.9 || >=17.5.0-rc-1, <17.10.3`; fixed in `16.10.17`, `17.4.9`, `17.10.3`

## Machine-written summary

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

> xwiki-platform-livetable-ui versions from 6.2.1 before 16.10.17, from 17.0.0-rc-1 before 17.4.9, and from 17.5.0-rc-1 before 17.10.3 are affected. An attacker can make about 768 requests to LiveTableResults to recover a user's password salt and hash one bit at a time, because an earlier fix was incomplete. Upgrade to 16.10.17, 17.4.9, or 17.10.3, or apply the patch manually to the wiki page XWiki.LiveTableResultsMacros.

## 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-rh28-mqj4-8x59>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
