Archived Security Brief

Saturday's security landscape delivers an urgent pre-deadline warning as seven CISA Known Exploited Vulnerabilities face federal compliance deadlines tomorrow, Sunday, October 26, with organizations entering a critical 24-hour countdown for mandatory remediation. This weekend brief follows an extraordinary week that produced two maximum-severity CVSS 10.0 vulnerabilities—CVE-2025-57870 affecting Esri ArcGIS Server and CVE-2025-61934 in Productivity Suite—while the patch availability crisis continues unabated at 0% for all 12 current critical vulnerabilities. With 22 actively exploited vulnerabilities tracked by CISA and five additional KEV entries already overdue from the October 22 deadline, federal agencies and their contractors face non-compliance risks heading into Sunday's enforcement moment. Security teams must activate weekend emergency operations to address tomorrow's federal deadlines while managing the sustained absence of vendor patches across critical infrastructure systems.

  • Federal Deadline Crisis: 7 CISA KEV vulnerabilities expire tomorrow (Sunday, October 26) requiring emergency weekend remediation—24-hour countdown active
  • Week's Maximum-Severity Events: Two CVSS 10.0 vulnerabilities discovered this week—CVE-2025-57870 (Esri ArcGIS Server SQL injection) and CVE-2025-61934 (Productivity Suite unrestricted IP binding)
  • Ongoing Non-Compliance: 5 CISA KEV vulnerabilities remain overdue from October 22 federal deadline with no remediation progress reported
  • Patch Availability Collapse: 0% patch availability sustained across all 12 critical vulnerabilities (CVSS 9.0+) affecting enterprise systems
  • Active Exploitation Scale: 22 CISA Known Exploited Vulnerabilities require immediate weekend action with federal enforcement implications
  • Weekend Operations Required: Security teams must staff emergency response for Sunday deadline with limited vendor support availability

Immediate action: Immediate action required before Sunday federal deadline: Deploy emergency patches for seven CISA KEV vulnerabilities expiring October 26 (CVE-2021-22555, CVE-2010-3962, CVE-2021-43226, CVE-2013-3918, CVE-2011-3402, CVE-2010-3765, CVE-2025-61882). Implement network segmentation and enhanced monitoring for CVSS 10.0 vulnerabilities CVE-2025-57870 (Esri ArcGIS Server) and CVE-2025-61934 (Productivity Suite) discovered this week. Activate weekend security operations center staffing to address 24-hour compliance countdown with federal enforcement implications for non-remediation.
