Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Yesterday's disclosure batch contains 10 critical-severity CVEs, an 11% increase from the prior day's 9 critical issues. High-priority vulnerabilities decreased 14% to 78, down from 91. The 14 actively exploited vulnerabilities include CVE-2026-1281 affecting Ivanti Endpoint Manager Mobile, CVE-2026-20805 targeting Microsoft Windows, and CVE-2026-20045 in Cisco Unified Communications Manager. Notable critical disclosures include CVE-2026-1699 (CVSS 10.0) in Eclipse Theia Website and CVE-2026-0963 (CVSS 9.9) in Crafty Controller's File Operations API. Patch availability stands at 0%, requiring organizations to implement compensating controls until vendor remediations become available.

  • 10 critical CVEs disclosed (CVSS 9.0+), up 11% from prior day
  • 78 high-priority CVEs (CVSS 7.0-8.9), down 14% from 91
  • 14 actively exploited vulnerabilities targeting Ivanti, Microsoft Windows, Cisco, and Zimbra
  • 0% patch availability across disclosed vulnerabilities
  • Critical issues affect Eclipse Theia, Crafty Controller, VMware vCenter Server, and Linux Kernel

Immediate action: Prioritize review of Ivanti Endpoint Manager Mobile, Microsoft Windows, Cisco Unified Communications Manager, and VMware vCenter Server deployments for actively exploited vulnerabilities. With no patches currently available, implement network segmentation, enhanced monitoring, and access restrictions as interim mitigations.

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.
