## Affected packages

- `org.jenkins-ci.plugins:job-import-plugin` (Maven): affected `<143.145.v48f9a`; fixed in `143.145.v48f9a`

## Machine-written summary

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

> Jenkins Job Import Plugin versions up to and including 143.v044a_2e819b_27 are vulnerable. An attacker with Overall/Read permission can enumerate the IDs of credentials stored in Jenkins because an HTTP endpoint lacks a permission check, and those IDs could help an attacker capture credentials through another vulnerability. Upgrade to version 143.145.v48f9a_a_6ff384 or later.

## 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-p8jh-4p5p-2rfp>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
