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.

A vulnerability has been reported in some versions of Internet Explorer. It is possible to inject JavaScript code into the browser history list, and execute it within any page context given appropriate user interaction.
Internet Explorer stores javascript: URLs in the browser history list. Script executed within the javascript: URL will inherit the security zone of the last viewed page. This provides protection against javascript: URLs included within a maliciously constructed web page. However, a user may navigate to a javascript: URL using the 'Back' button in their browser. This may result in the injected script code executing within the context of another page.
This behavior has been reported in versions 6.0 and 5.5 of IE. Other versions of Internet Explorer may share this vulnerability. This has not, however, been confirmed.
