CVSS 3.1
4.3 mediumCVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:NCVE-2023-1920
The WP Fastest Cache plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.1.2. This is due to missing or incorrect nonce validation on the wpfc_purgecache_varnish_callback function. This makes it possible for unauthenticated attackers to purge the varnish cache via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
