Threat Intelligence
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. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the parsing process of text models due to insufficient validation of child and split array values. An attacker can achieve arbitrary memory writes by supplying a specially crafted model file with invalid node references, leading to out-of-bounds writes at attacker-controlled offsets in the leaf_depth_ buffer during feature contribution computation.
Note: This is only exploitable if a user loads a malicious model file.
