Critical and high-severity CVEs 458 above median
What's new The number of Critical and high-severity CVEs rose to 615 in the week of Nov. 2, according to NIST National Vulnerability Database data through Nov. 11.
Why it matters Critical and high-severity CVEs: 615 records in the week of Nov. 2, 2026 (Monday to Sunday), against a median of 157 a week over the previous 6 weeks, according to NIST National Vulnerability Database (PostNewz pn_records rows).
This increase matters because it may indicate a growing number of potential security vulnerabilities that could impact computer systems and data.
The current weekly count of 615 Critical and high-severity CVEs is compared with a median weekly count of 157 over the earlier six weeks.
The median is the middle value in a list of numbers, and in this case, it represents the typical number of Critical and high-severity CVEs per week over the earlier period.
A CVE, or Common Vulnerabilities and Exposures, is a list of publicly known cybersecurity vulnerabilities, and the CVSS score is a measure of the severity of a vulnerability, with higher scores indicating greater severity.
Examples of Critical and high-severity CVEs in the week of Nov. 2 include CVE-2026-96146, which has a CVSS score of 7.5, and CVE-2026-118904, which has a CVSS score of 8.1.
Room for disagreement
The count of 615 may not be representative of future weeks, as the number of CVEs can fluctuate over time.
