To improve control over your tests, you can use the --severity-threshold option for the snyk test command with one of the supported levels: low|medium|high|critical. With this option, only vulnerabilities of the specified level or higher are reported.
$ snyk test --severity-threshold=medium
Setting --severity-threshold to low has the same effect as running the command without specifying the threshold; all vulnerabilities are reported.
Note: The --severity-threshold option is available with the snyk test, snyk code, snyk container, and snyk iac test commands. See the CLI commands help pages for each command for details.
