## Machine-written summary

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

> Keycloak's keycloak-services package, versions before 22.0.10 and from 23.0.0 before 24.0.3, is vulnerable. The source says a flaw in redirect_uri validation allows bypassing hosts that are explicitly allowed; it gives few details on the required access or the full impact. Upgrade to version 22.0.10 or 24.0.3, depending on your release line.

## 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-mrv8-pqfj-7gp5>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
