GHSA-4w8r-3xrw-v25g

Craft CMS Remote Code Execution vulnerability

Quick fix

GHSA-4w8r-3xrw-v25g — craftcms/cms: upgrade to the fixed version with the command below.

composer require craftcms/cms:^4.4.15

Details

### Impact

This is a high-impact, low-complexity attack vector. Users running Craft installations before 4.4.15 are encouraged to update to at least that version to mitigate the issue.

### Mitigations

* This has been fixed in Craft 4.4.15. You should ensure you’re running at least that version. * Refresh your security key in case it has already been captured. You can do that by running the `php craft setup/security-key` command and copying the updated `CRAFT_SECURITY_KEY` environment variable to all production environments. * If you have any other private keys stored as environment variables (e.g., S3 or Stripe), refresh those as well. * Out of an abundance of caution, you may want to force all your users to reset their passwords in case your database was compromised. You can do that by running `php craft resave/users --set passwordResetRequired --to "fn() => true"`.
