CVE: the unique reference for a known vulnerability
A CVE (Common Vulnerabilities and Exposures) is a unique identifier assigned to a publicly documented security vulnerability, in the format CVE-year-number, enabling everyone to refer to it unambiguously.
Definition
This system, maintained by a non-profit organization in coordination with many vendors, prevents the same flaw from being described differently across sources. Each CVE is generally accompanied by a severity score (CVSS) that helps prioritize its remediation.
The number of CVEs published each year continues to grow, making it impossible to fix everything immediately. That is why prioritization, by combining severity, actual exposure, and observed active exploitation, has become a discipline in its own right within patch management.
Key points
A standardized identifier
Each public vulnerability receives a unique reference that can be used by all security tools and teams.
An associated severity score
The CVSS score helps assess the relative criticality of a flaw, without replacing contextual analysis.
Essential prioritization
Given the volume of CVEs published each year, patch prioritization has become a discipline in its own right.
How BCIT can support you
Prioritizing patches according to the CVEs that are genuinely relevant to your context is part of our security audits.
Frequently asked questions ❓
Should every CVE be fixed as soon as it is published?
In practice, this is rarely possible: prioritization based on actual exposure and observed active exploitation is necessary.
Is the CVSS score enough to assess risk?
No, it must be combined with the real context: a critical CVE on a non-exposed system carries less weight than a medium-severity CVE that is being actively exploited.

Do you know which vulnerabilities to fix first?
Let’s structure a prioritization approach tailored to your actual exposure, beyond the theoretical score alone.
