Description

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".
