What is the difference between CVSS base, temporal, and environmental scores?

Base score: intrinsic vulnerability characteristics (0-10). Temporal score: adjusts for exploit code availability and patch status - lowers score if no public exploit exists. Environmental score: adjusts for your specific deployment (internet-facing vs internal, data sensitivity).

Should I use CVSS score alone to prioritize vulnerabilities?

No. CVSS base score does not account for your environment. Add context: is the vulnerable service internet-facing? Does public exploit code exist? Is the affected component actually in use? CISA KEV (Known Exploited Vulnerabilities) is a better prioritization signal than CVSS score alone.
