## Machine-written summary

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

> Zend Framework zendframework/zendframework1 versions from 1.0.0 before 1.11.12, and from 1.12.0-rc1 before 1.12.0, are affected. A remote attacker can send an XML-RPC request containing an external entity reference in a DOCTYPE element to read arbitrary files or make TCP connections from the server. Upgrade to 1.11.12 or 1.12.0.

## 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-7pg4-5233-82jv>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
