Organizations generally can only fix between 5% and 20% of vulnerabilities each month, EPSS claims. Fewer than 10% of published vulnerabilities are ever known to be exploited in the wild.

EPSS shows an 82% improvement over previous versions. The EPSS team claims an 82% performance improvement in EPSS 3.0 over previous versions along with covering the evolving vulnerability landscape.

Manipulating EPSS Output with Adversarial Attack. The objective of Ikar’s proof-of-concept was to manipulate the probability estimate provided as output when using the EPSS for a chosen vulnerability.

Also, EPSS is, by design, inaccurate for vulnerabilities previously observed to be exploited,” the NIST authors wrote. However, the standardization agency also noted that LEV has an unknown margin of ...
