- `getformwork/formwork` (Packagist): affected `>=2.0.0-beta.1, <2.0.0-beta.4`; fixed in `2.0.0-beta.4`

## Machine-written summary

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

> Formwork (Packagist package getformwork/formwork) versions 2.0.0-beta.1 up to but not including 2.0.0-beta.4 are affected. An attacker with administrator access, or with a privileged account, can submit an invalid user role value that makes the user's data unloadable, causing a 500 error that takes down the entire site and administration panel until the account file is restored by hand. Upgrade to 2.0.0-beta.4, which adds validation for select fields.

## 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-c85w-x26q-ch87>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
