Severity scores defined by OISF and CVSS may vary due to how we assess and evaluate impact. While CVSS has a more generic view on vulnerabilities and will penalize any network-related issues, for instance, OISF considers Suricata context as the baseline (thus, as example, affecting the network isn’t taken into account).

Security Issues
Note that we have refined our severities sometime back. CRITICAL severity is reserved for issues affecting Tier 1 features enabled by default, involving remotely triggerable traffic-based code execution. HIGH severity also covers Tier 1 features enabled by default, where there’s possible loss of visibility or availability.
If you think you’ve encountered a security vulnerability, please see how to report a security issue.
