Am I affected?

W3 Total Cache w3-total-cache

  1. Affected0.9.2.6 – 0.9.3
  2. Patched in0.9.4

Update to 0.9.4 or newer.

You are affected if you run 0.9.2.6 – 0.9.3. Version 0.9.4 and later are not affected by this issue.

  • Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under W3 Total Cache.

  • No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

  1. Update to version 0.9.4, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch W3 Total Cache to get an email when the next vulnerability is published.
