No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The Cache Enabler WordPress plugin before 1.8.17 does not validate a URL before using it to build a filesystem path in its cache purge routine, and does not confine the resulting deletion to the cache directory, allowing unauthenticated users to delete arbitrary files and directories on sites where another installed Cache Enabler WordPress plugin before 1.8.17 or passes a request-derived URL to its public cache-clearing hook.
