Until a fix ships, reduce exposure:
  • Restrict access to the affected service or interface to trusted networks.
  • Disable the affected feature if you do not need it.
  • Watch the vendor advisory for a firmware or software update.

What to do

Prioritize this fix. Exploit code is public, so attacks can follow quickly.

  1. Check whether you run FlowCI flow-core-x and which version.
  2. No patched version is listed yet. Limit access to the affected service to trusted networks, and disable the feature if you can.
  3. Subscribe to the vendor advisory so you learn when a fix ships.
  4. Review logs and exposed services for signs of earlier compromise.
