CVE stands for Common Vulnerabilities and Exposures, a cybersecurity abbreviation.

The public catalog that gives each disclosed security vulnerability a unique identifier, such as CVE-2021-44228 for Log4Shell, so vendors, researchers and tools can refer to the same flaw.

Example: The scanner found CVE-2024-3400 on the firewall, so patch it before the weekend.

Usage notes

Launched by MITRE in 1999 and funded by the US Cybersecurity and Infrastructure Security Agency. Identifiers are assigned by MITRE and hundreds of CVE Numbering Authorities, including major software vendors. In April 2025 MITRE's funding contract nearly lapsed before CISA extended it at the last minute, and a separate CVE Foundation was formed to safeguard the program. Severity scores come separately, from CVSS.
