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 Use After Free when executing a :s
command for the first time and using a sub-replace-special atom inside the substitution part. An attacker can cause freeing of memory which may later then be accessed by the initial :s
command by making a recursive :s
call.
Note:
This is only exploitable if the user intentionally executes the payload and it seems to work only reliably for the very first :s
command. It may also cause a crash.
