CVE-2022-40797 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Roxy Fileman 1.4.6 allows Remote Code Execution via a .phar upload, because the default FORBIDDEN_UPLOADS value in conf.json only blocks .php, .php4, and .php5 files. (Visiting any .phar file invokes the PHP interpreter in some realistic web-server configurations.). EPSS estimates a 2.56% chance of exploitation in the next 30 days.
