Vulnerability severity levels (ULTIMATE)
GitLab vulnerability analyzers attempt to return vulnerability severity level values whenever
possible. The following is a list of available GitLab vulnerability severity levels, ranked from
most to least severe:
CriticalHighMediumLowInfoUnknown
Most GitLab vulnerability analyzers are wrappers around popular open source scanning tools. Each
open source scanning tool provides their own native vulnerability severity level value. These values
can be one of the following:
To provide consistent vulnerability severity level values, the GitLab vulnerability analyzers
convert from the above values to a standardized GitLab vulnerability severity level, as outlined in
the following tables:
