Vulnerabilities

Last updated 33 minutes ago
Filters
Severity
Critical Severity
CVSS Score Range: 9.0–10.0
Critical severity vulnerabilities (CVSS 9.0–10.0). These represent the highest impact issues.
High Severity
CVSS Score Range: 7.0–8.9
High severity vulnerabilities (CVSS 7.0–8.9). Serious vulnerabilities that should be prioritized soon after critical fixes.
Medium Severity
CVSS Score Range: 4.0–6.9
Medium severity vulnerabilities (CVSS 4.0–6.9). Important issues that meaningfully reduce security confidence.
Low Severity
CVSS Score Range: < 4.0
Low severity vulnerabilities (CVSS < 4.0). Hygiene issues that can accumulate but pose lower immediate risk.
Unknown Severity
CVSS Score Range: No score
Vulnerabilities without an assigned CVSS score. Severity is not determinable from available data.
