## Machine-written summary

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

> GHSA-985r-q3qp-299h affects the Packagist packages thorsten/phpmyfaq and phpmyfaq/phpmyfaq before 4.1.4. The source says the 4.1.3 fix for GHSA-xvp4-phqj-cjr3 was incomplete, leaving the editUser() and updateUserRights() methods without authorization checks. An administrator holding only the edit_user right, but not SuperAdmin, could reportedly set the is_superadmin flag on accounts, including their own, or grant rights to other accounts. Upgrade to version 4.1.4, which is listed as the fixed version.

## 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-985r-q3qp-299h>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
