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.

remdex/livehelperchat is a package that offers live support for your website. Featuring web and desktop clients. Compatible Windows, Linux, Mac. Desktop client powered by QT. Supports mobile phones based on XMPP service providers (GTalk, Xabber, Mono etc.)
Affected versions of this package are vulnerable to Information Exposure due to the option of specifying a file location of the city database file, which gives an indication if the file exists or not based on the server's response. An attacker can use this information to determine which files exist and do not exist in order to better profile the system and gain more data.
Go to /site_admin/chat/geoconfiguration#!#geoconfiguration
Scroll to *Location of city database`
Enter any file location (EX: /etc/passwd2)
Click save
Notice that the file path is highlighted in red, indicating that it doesn't exist.
Then enter a file that does exist (/etc/passwd)
Click save
Notice that the file path is now highlighted in green, indicating that the file exists
