CVSS v3.1 Calculator

Calculate the severity of software vulnerabilities using the Common Vulnerability Scoring System (CVSS) v3.1.

Exploitability Metrics

Reflects the context by which vulnerability exploitation is possible.
Describes the conditions beyond the attacker's control that must exist in order to exploit the vulnerability.
The level of privileges an attacker must possess before successfully exploiting the vulnerability.
Whether the vulnerability can be exploited without interaction from an additional user.

Impact Metrics

Whether a vulnerability in one software component impacts resources beyond its security boundary.
Impact on the confidentiality of the data managed by the software.
Impact on the integrity (correctness) of the data managed by the software.
Impact on the availability of the impacted component.

Pro Tip

Use the Scope metric carefully. If an exploit impacts a component beyond its security boundary (e.g., a sandbox escape), set Scope to Changed.
