What is the regex for cve identifier?

The regex pattern for cve identifier is `^CVE-\d{4}-\d{4,}$`. This pattern validates common vulnerabilities and exposures (cve) id.

How do I use this regex in JavaScript?

In JavaScript, create the regex with `const regex = /^CVE-\d{4}-\d{4,}$/;` and test with `regex.test(yourValue)`. It returns `true` if the value matches.

How do I use this regex in Python?

In Python, use `import re; re.match(r'^CVE-\d{4}-\d{4,}$', value)`. The raw string prefix (`r`) prevents Python from interpreting backslashes as escape characters.

Is this regex case-sensitive?

By default, yes. To make it case-insensitive, add the `i` flag in JavaScript (`/^CVE-\d{4}-\d{4,}$/i`) or use `re.IGNORECASE` in Python.
