Overview
CVE vulnerability lookup by ID (CVE-2021-44228): the description, CVSS score and severity, whether CISA lists it as exploited in the wild (KEV) and since when, the EPSS probability of exploitation in the next 30 days, the weakness (CWE), affected products with fixed versions, and patch and advisory links. Use to triage a security alert, decide what to patch first, or check an advisory before upgrading a dependency.
