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.

to version 0.11.2 or higher.
unearth is an A utility to fetch and download python packages
Affected versions of this package are vulnerable to Improper Input Validation through the pdm.lock
file. An attacker can manipulate the dependency management system to install malicious packages by crafting a malicious pdm.lock
file. This can lead to arbitrary code execution on install or downgrade attacks by only changing the version.
This is only exploitable if the version is parseable as a version and the filename is a prefix of the project name.
