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.

org.eclipse.jetty:jetty-http is an is a http module for jetty server.
Affected versions of this package are vulnerable to Improper Handling of Length Parameter Inconsistency via the HttpParser.java
component due to accepting the +
character proceeding the content-length value in a HTTP/1
header field. An attacker can use jetty in combination with a server that does not close the connection after rejecting such request and after sending a 400 response. This could result in request smuggling.
