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.

source: https://www.securityfocus.com/bid/8853/info A vulnerability has been discovered in the Opera web browser that could lead to remote code execution. The problem is said to trigger when handling malformed HTML HREF values and may result in a buffer overrun occuring within heap memory. As a result of this issue, an attacker may be capable of executing arbitrary code on a victim user by coaxing them to a malicious web site, or possibly by transmitting a malicious HTML e-mail message to an Opera mail client. <a href="file://server%%[many % characters]%%text" ></a>
