CVE (Common Vulnerabilities and Exposures) is a standardized identifier for publicly known cybersecurity vulnerabilities. Each CVE ID (e.g., CVE-2021-44228 for Log4Shell) uniquely identifies a specific flaw, making it easier for security teams to track, prioritize, and patch vulnerabilities across different tools and databases.
