What it means
These systems answer different questions. An identifier is not a risk score, a severity score is not exploit prediction, and a weakness class is broader than one product flaw.
Why it matters
Using the references together improves communication and prioritization when combined with asset exposure, business impact, and current threat activity.
Practical focus
- Use CVE for consistent vulnerability identification
- Use CWE to understand recurring weakness patterns
- Interpret CVSS in environmental context
- Use EPSS and active-exploitation evidence as prioritization inputs
Common mistakes
- Treating CVSS as business risk
- Assuming a CVE means every installation is vulnerable
- Ignoring compensating controls and exposure
