Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

This disclosure activity includes 9 critical CVEs (CVSS 9.0+), representing a 50% increase from yesterday's 6 critical vulnerabilities. High-priority CVEs rose to 54, up 17% from the previous day's 46 entries. Thirteen vulnerabilities are confirmed actively exploited, including CVE-2025-6218 affecting RARLAB WinRAR, CVE-2025-62221 in Microsoft Windows, and CVE-2025-48633 targeting Android Framework. Critical severity issues concentrate in Shiguangwu sgwbox products with multiple CVSS 9.8 vulnerabilities (CVE-2025-14705 through CVE-2025-14709), alongside Fox LMS CVE-2025-14156 and MooreThreads CVE-2025-65213. Patch availability stands at 0%, requiring organizations to implement compensating controls until vendor remediation becomes available.

  • 9 critical CVEs disclosed, up 50% from yesterday's 6 critical vulnerabilities
  • 54 high-priority CVEs identified, a 17% increase from the previous day
  • 13 actively exploited vulnerabilities including WinRAR, Microsoft Windows, Android Framework, and GeoServer
  • 0% patch availability necessitates compensating controls across all affected systems
  • Multiple critical vulnerabilities in Shiguangwu sgwbox, Fox LMS, DeepChat, and OpenShift products

Immediate action: Prioritize mitigation for actively exploited CVEs affecting WinRAR (CVE-2025-6218), Microsoft Windows (CVE-2025-62221), and Android Framework (CVE-2025-48633 and CVE-2025-48572). With no patches currently available, implement network segmentation, restrict access to affected services, and enable enhanced logging for detection. Security teams should maintain elevated monitoring throughout the week given the high volume of actively exploited 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.
