Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
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.

Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity through the verify
process. An attacker can manipulate the verification process by creating a mismatched bundle that passes cryptographic checks but is not actually associated with the artifact in question.
Note:
sigstore-gradle-plugin
and sigstore-maven-plugin
are not affected by this as they only provide signing functionality.
Verifiers can recreate the log entry and compare it to the provided log entry or contact the log and discover if the artifact signing event has indeed been added to the log.
