Published by the GitHub Advisory Database at 2 Apr 2025, 15:31 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `org.jenkins-ci.main:jenkins-core` (Maven): affected `>=2.500, <2.504 || <2.492.3`; fixed in `2.504`, `2.492.3`

## Machine-written summary

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

> Jenkins core (org.jenkins-ci.main:jenkins-core) versions from 2.500 up to but not including 2.504, and versions before 2.492.3, are affected. An attacker who has the Computer/Create permission but not Computer/Configure can copy an agent because an HTTP endpoint lacks a permission check, which exposes encrypted secrets in the agent's configuration. Upgrade to Jenkins 2.504 or LTS 2.492.3.

## 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-wr6w-jxg7-qpfh>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
