CVEs & Vulnerabilities: Live Threat Intelligence

Tens of thousands of vulnerabilities (CVEs) are published every year — far more than any team can patch immediately. The central challenge is prioritization: which flaws do you fix first? This page aggregates the latest CVE and vulnerability reporting from authoritative sources, with analysis of how to triage below.

CVEs, CVSS and the NVD

A CVE is a unique public identifier for a specific vulnerability, so everyone can refer to the same flaw consistently. The CVSS score rates its severity from 0 to 10, and the National Vulnerability Database (NVD) enriches each CVE with that score and affected-product data. But a CVE record identifies a flaw and CVSS rates its potential severity — neither tells you whether anyone is actually exploiting it.

Prioritizing by real risk

Relying on CVSS alone leads teams to drown in "critical" vulnerabilities, many of which pose little real-world risk, while genuine threats hide among lower scores. Smart prioritization blends three signals: is it being actively exploited (CISA's Known Exploited Vulnerabilities catalog confirms in-the-wild exploitation — patch these first), how likely is exploitation (the EPSS model estimates probability), and how exposed and critical is the affected asset. This is the foundation of risk-based vulnerability management.

What to watch

• CISA KEV additions — confirmed exploitation; top patching priority.
• Critical RCE flaws in internet-facing software — favorite targets for mass exploitation.
• Proof-of-concept releases — public exploit code sharply raises exploitation likelihood.

How to act

Patch anything in CISA KEV immediately, then prioritize high-EPSS vulnerabilities on exposed systems, then order the rest by CVSS and asset criticality. Re-evaluate continuously, since exploitation status changes daily. Our guides cover what a CVE is, CVSS vs EPSS prioritization, and zero-day vulnerabilities.
