Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Friday's vulnerability landscape includes 9 critical CVEs (CVSS 9.0+), a 44% decrease from Thursday's 16 critical disclosures. High-priority vulnerabilities remain steady at 91 (down 5% from 96), while actively exploited CVEs hold constant at 14 KEV entries. Notable critical vulnerabilities include CVE-2026-1340, a code injection flaw in Ivanti Endpoint Manager Mobile enabling unauthenticated RCE, and CVE-2026-1453, a missing authentication vulnerability in KiloView Encoder Series allowing unauthorized admin account manipulation. The 14 actively exploited vulnerabilities span multiple vendors including Microsoft Windows and Office, Cisco Unified Communications Manager, VMware vCenter Server, and Zimbra Collaboration Suite. Current patch availability sits at 0%, requiring organizations to implement compensating controls until vendor fixes become available.

  • 9 critical CVEs disclosed (44% decrease from Thursday's 16)
  • 91 high-priority vulnerabilities (5% decrease from 96)
  • 14 actively exploited CVEs affecting Microsoft, Cisco, VMware, Zimbra, and Linux systems
  • 0% patch availability requires compensating controls and monitoring
  • Ivanti EPMM and KiloView Encoder Series face critical authentication and code injection flaws

Immediate action: Priority assessment needed for environments running Microsoft Windows/Office, Cisco UCM, VMware vCenter, and Zimbra—all present in the active exploitation list. With zero patches currently available, implement network segmentation, enhanced monitoring, and access restrictions for affected systems until vendor remediations are released.

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.
