Qualys Vulnerability Score (QVS) is a Qualys-assigned score for a vulnerability based on multiple factors associated with the CVE such as CVSS and external threat indicators like active exploitation, exploit code maturity, CISA known exploitable and many more.


The following formula is used to calculate the QVS for specific CVE:

QVS = QVD - CIDs
