Published by the GitHub Advisory Database at 14 Oct 2024, 20:56 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `org.keycloak:keycloak-core` (Maven): affected `<24.0.7 || >=25.0.0, <25.0.4`; fixed in `24.0.7`, `25.0.4`

## Machine-written summary

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

> Keycloak (org.keycloak:keycloak-core) versions before 24.0.7 and from 25.0.0 before 25.0.4 accept expired one-time passcodes when FreeOTP is used with the default 30-second token period. Such codes remain valid for about 60 seconds instead of 30, so two codes are valid at once, which widens the window for account compromise. Upgrade to version 24.0.7 or 25.0.4.

## 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-xmmm-jw76-q7vg>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
