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.

getgrav/grav is a Modern, Crazy Fast, Ridiculously Easy and Amazingly Powerful Flat-File CMS.
Affected versions of this package are vulnerable to Code Injection due to improper handling of user input in the CMS's templating engine. An attacker can execute arbitrary code on the server by crafting malicious input that exploits the template injection vulnerability. This is only exploitable if the attacker has authenticated access with at least editor permissions.
{% set arr = {'1':'system', '2':'foo'} %}
{{ var_dump(grav.twig.twig_vars['config'].set('system.twig.safe_functions', arr)) }}
