## Affected packages

- `craftcms/cms` (Packagist): affected `>=5.0.0-RC1, <5.8.21 || >=4.0.0-RC1, <4.16.17`; fixed in `5.8.21`, `4.16.17`

## Machine-written summary

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

> Craft CMS (craftcms/cms) versions 4.0.0-RC1 through 4.16.16 and 5.0.0-RC1 through 5.8.20 are vulnerable to a Twig template injection that can lead to remote code execution. An attacker needs administrator access to the Control Panel with allowAdminChanges enabled, or a non-administrator account with access to the System Messages utility, and can then craft a malicious payload using the Twig map filter in Twig-accepting fields. Upgrade to 4.16.17 or 5.8.21, which contain the fix.

## 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-742x-x762-7383>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
