CVE-2019-6726
The WP Fastest Cache plugin through 0.8.9.0 for WordPress allows remote attackers to delete arbitrary files because wp_postratings_clear_fastest_cache and rm_folder_recursively in wpFastestCache.php mishandle ../ in an HTTP Referer header.
Does this matter?
Lower severity and a low EPSS score (4.35%). Track it; it rarely justifies an emergency change on its own.
