Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Sunday's security landscape marks a critical federal compliance deadline as 5 CISA KEV vulnerabilities expire TODAY requiring immediate patching for Apple iOS (CVE-2022-48503), Microsoft Windows (CVE-2025-33073), Kentico CMS (CVE-2025-2746, CVE-2025-2747), and Oracle E-Business Suite (CVE-2025-61884). In an unprecedented weekend development, zero critical CVEs (CVSS 9.0+) were disclosed for the first time in months, representing a 100% drop from Saturday's 6 vulnerabilities. However, the 22 high-priority CVEs demand continued vigilance despite the 76% decrease from yesterday's 93 disclosures. Federal agencies face compliance enforcement today while patch availability improved marginally to 21%, leaving 79% of vulnerabilities without vendor-provided fixes as organizations navigate this critical deadline day.

  • FEDERAL DEADLINE TODAY: 5 CISA KEV vulnerabilities expire November 9 requiring immediate compliance
  • Zero Critical CVEs: First time in months with no CVSS 9.0+ disclosures (down 100% from Saturday)
  • High Priority Drop: 22 vulnerabilities (down 76% from yesterday's 93)
  • Patch Availability: 21% (marginal 3% improvement, but 79% still lack vendor patches)
  • Urgent KEV Patches: Apple iOS, Microsoft Windows, Kentico CMS, Oracle E-Business Suite deadline TODAY
  • Sunday Compliance: Federal agencies must demonstrate KEV remediation before business hours Monday

Immediate action: Immediate action: Federal agencies and organizations must deploy emergency patches TODAY for CVE-2022-48503 (Apple iOS), CVE-2025-33073 (Microsoft Windows), CVE-2025-2746/CVE-2025-2747 (Kentico CMS), and CVE-2025-61884 (Oracle E-Business Suite) to meet November 9 federal deadline. Security teams should verify patch deployment, document compliance, and prepare deadline reports before end of business. Organizations unable to patch must implement compensating controls and document exceptions immediately.

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.
