What is CVE-2023-1929?

The WP Fastest Cache plugin for WordPress suffers from a vulnerability that allows unauthenticated users with subscriber-level access to purge the varnish cache. This is due to a missing capability check in the wpfc_purgecache_varnish_callback function, potentially leading to unauthorized data modification. Users are urged to update to the latest version of the plugin to mitigate this risk.
