GHSA-4w8r-3xrw-v25g Craft CMS Remote Code Execution vulnerability

• Packagist craftcms/cms: >= 4.0.0-RC1, < 4.4.15 → fixed in 4.4.15

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"`.
