Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Monday's vulnerability disclosure reveals two newly published critical vulnerabilities and 17 high-priority CVEs as security teams return to the work week. Seven actively exploited CISA KEV vulnerabilities continue to require remediation. The overall critical CVE frequency shows an 83% decrease compared to historical averages, maintaining the reduced disclosure activity observed over the weekend period.

  • Two newly published critical vulnerabilities disclosed (CVSS 9.0+), representing new issues requiring assessment
  • Seventeen high-priority vulnerabilities (CVSS 7.0-8.9), unchanged from Sunday's count
  • Seven actively exploited CISA KEV vulnerabilities requiring remediation, unchanged from Sunday
  • Critical CVE frequency decreased 83% compared to historical average, reflecting continued below-average disclosure activity

Immediate action: Security teams should assess the two newly published critical vulnerabilities and review the 17 high-priority CVEs. Organizations should prioritize remediation of the seven actively exploited CISA KEV vulnerabilities.

How to read this brief

CVSS score (e.g. 9.1) — severity from 0–10. Red marks critical (9+), orange high (7–8.9).

Exploitability — how hard the flaw is to attack, read from the CVSS vector:

  • Network / Adjacent / Local / Physical — how close an attacker must get. Network means reachable over the internet.
  • No / Low / High privileges — the access they need first. No privileges means no login required.
  • No interaction / User interaction — whether a victim has to do something (open a file, click a link). No interaction means fully automatable.

The lower the bar on all three, the easier to exploit at scale — “Network · No privileges · No interaction” is the worst case: hit from anywhere, no credentials, no victim action.

Actively exploited — confirmed under attack in the wild (CISA’s Known Exploited Vulnerabilities catalog). Prioritize these regardless of score.

EPSS · Nth percentile — FIRST.org’s estimated chance a flaw is exploited within 30 days. We flag it only in the top 10% — a statistical signal it’s unusually likely to be targeted, separate from whether attacks are confirmed.
