Where can I find description about severity for SAST?


I would like to ask question about online document.

I started to use trial license for gold subscription to see how code scan (SAST) works.

I’d like to know what does these severites means but there seems to no description about them in the doc.

Is there any blog or other page in the doc where I could find the meaning of each severity .
I am expecting something similar to description in severity level of syslog .
