Exploitation status

  • CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
  • US federal civilian agencies are required to remediate it by 2022-04-15. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.
