Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Friday's vulnerability disclosure yielded no new critical CVEs (CVSS 9.0+), a notable decrease from Thursday's 29 critical issues. High-priority vulnerabilities remained steady at 95, representing a 5% decrease from the prior day's 100. Eleven actively exploited CVEs appear in CISA's Known Exploited Vulnerabilities catalog, including CVE-2025-66644 affecting Array Networks ArrayOS AG, CVE-2025-6218 targeting RARLAB WinRAR, and CVE-2025-62221 impacting Microsoft Windows. Additional KEV entries include CVE-2025-14174 in Google Chromium, CVE-2025-14611 affecting Gladinet CentreStack/Triofox, and CVE-2025-43529 impacting multiple Apple products. Patch availability stands at 0%, indicating organizations should implement compensating controls while monitoring for vendor updates.

  • Zero critical CVEs disclosed, down 100% from Thursday's 29 critical vulnerabilities
  • 95 high-priority CVEs tracked, a 5% decrease from the prior day's 100
  • 11 actively exploited vulnerabilities including D-Link routers, WinRAR, Microsoft Windows, and Google Chromium
  • 0% patch availability for disclosed vulnerabilities requires compensating controls
  • Affected systems span enterprise infrastructure: Array Networks, Sierra Wireless AirLink, ASUS Live Update, and GeoServer

Immediate action: Organizations using Array Networks, Microsoft Windows, Google Chrome, Apple products, WinRAR, or Gladinet solutions should prioritize reviewing the eleven actively exploited vulnerabilities. With zero patches currently available, implement network segmentation, enhanced monitoring, and access restrictions for affected systems.

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.
