## Affected packages

- `backpack/crud` (Packagist): affected `>=6.0.0, <6.8.14 || >=7.0.0, <7.0.38`; fixed in `6.8.14`, `7.0.38`

## Machine-written summary

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

> Backpack CRUD versions 6.0.0 to before 6.8.14 and 7.0.0 to before 7.0.38 are vulnerable to stored cross-site scripting in the color column type, where values are rendered unescaped by default. An attacker who can write an arbitrary string into a color column can run JavaScript in the browser of any user who views the list, including administrators. Upgrade to 6.8.14 or 7.0.38. Until then, validate color values against a strict hex color pattern in the model before they are stored.

## 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-mmg4-322v-6jvc>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
