The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Start learningUpgrade dns-sync to version 0.1.1 or greater.
The dns-sync library for node.js allows resolving hostnames in a synchronous fashion. All versions of dns-sync prior to the release 0.1.3 were vulnerable to arbitrary command execution via maliciously formed hostnames.
For example:
var dnsSync = require('dns-sync');
console.log(dnsSync.resolve('$(id > /tmp/foo)'));
This is caused by the hostname being passed through a shell as part of a command execution.
