During the analysis SonarQube divides the metric infringements, named Issues, into three categories in addition to severity: Code Smell: An example for this are the cyclomatic complexities, as Deprecated marked Code or useless mathematical functions, for example the rounding of constants. If so, then it's a Security Hotspot rule. Security Hotspots are not assigned severities as it is unknown whether there is truly an underlying vulnerability until they are reviewed. Then we assess whether the impact and likelihood of the Worst Thing (see How are severity and likelihood decided?, below) are high or low, and plug the answers into a truth table: To assess the severity of a rule, we start from the Worst Thing (see How are severities assigned?, above) and ask category-specific questions.
