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:

• Critical
• High
• Medium
• Low
• Info
• Unknown

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:

Native vulnerability severity level type	Examples
String	WARNING, ERROR, Critical, Negligible
Integer	1, 2, 5
CVSS v2.0 Rating	(AV:N/AC:L/Au:S/C:P/I:P/A:N)
CVSS v3.1 Qualitative Severity Rating	CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

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:

Fuzz Testing

All fuzz testing results are reported as Unknown. They should be reviewed and triaged manually to find exploitable faults to prioritize for fixing.
