Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Wednesday's vulnerability disclosure includes 11 critical CVEs (CVSS 9.0+), a 22% increase from yesterday's 9 critical issues. High-priority vulnerabilities reached 71 entries, up 31% from yesterday's 54, indicating sustained disclosure activity mid-week. Fourteen actively exploited vulnerabilities require attention, including CVE-2025-59718 affecting Fortinet products, CVE-2025-6218 in WinRAR, and CVE-2025-62221 targeting Microsoft Windows. Notable critical disclosures include CVE-2025-63414 (CVSS 10.0) path traversal in Allsky WebUI, CVE-2025-37164 (CVSS 10.0) remote code execution in HPE products, and CVE-2025-46295 (CVSS 9.8) affecting Apache Commons Text. Patch availability stands at 0%, requiring organizations to prioritize compensating controls until vendor fixes become available.

  • 11 critical CVEs disclosed, up 22% from yesterday's 9 critical vulnerabilities
  • 71 high-priority CVEs represent a 31% increase from yesterday's 54 entries
  • 14 actively exploited vulnerabilities affecting Fortinet, WinRAR, Microsoft Windows, and Google Chromium
  • 0% patch availability requires immediate compensating control deployment
  • Critical systems affected include HPE products, Apache Commons Text, NVIDIA Isaac Lab, and Open edX Platform

Immediate action: Prioritize network segmentation and access restrictions for systems affected by KEV entries, particularly Fortinet appliances, WinRAR installations, and Windows environments. With zero patches currently available, implement web application firewalls, disable unnecessary services, and enhance monitoring for exploitation attempts. Mid-week timing allows for coordinated response planning before weekend staffing reductions.

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.
