Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Wednesday shows a higher-than-usual volume: 15 critical CVEs (up 150% from Tuesday's 6) and 87 high-priority vulnerabilities (up 358% from 19). In total, 304 CVEs were recorded (up 328% versus Tuesday). Current patch availability is 15% (down 81 points from Tuesday's 96%). CISA added 2 new KEV vulnerabilities, bringing the catalog referenced here to 15. With about 85% of the critical items currently without vendor patches, teams should focus on monitoring and mitigations while patches are pending.

  • 15 critical CVEs (+150% increase; highest since November 1)
  • 87 high-priority CVEs (+358% increase)
  • 304 total CVEs (+328% increase; ~4.3× Tuesday's count)
  • 15% patch availability (−81 points from Tuesday's 96%)
  • 15 CISA KEV vulnerabilities (+2 new additions)
  • Approximately 85% of critical vulnerabilities currently lack vendor patches

Immediate action: Recommended actions: Prioritize review of the 15 critical CVEs and the 15 CISA KEV items. For issues without patches, apply temporary mitigations where feasible (e.g., network segmentation, access control tightening, and enhanced monitoring). Plan remediation windows as patches become available and track vendor updates closely.

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.
