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.

Crass is a Ruby CSS parser that's fully compliant with the CSS Syntax Level 3 specification. Prior to 1.0.7, when Crass parses input containing non-ASCII characters, inefficiencies in tracking the positions of multi-byte characters result in superlinear parsing time. An attacker-controlled CSS input consisting of many non-ASCII characters can therefore cause excessive CPU consumption and potentially denial of service. This issue is fixed in version 1.0.7.
