Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Friday's vulnerability disclosures are dominated by multiple critical flaws in Veeam Backup & Replication, with four CVEs scoring 9.9 and one at 9.1, presenting significant risk to enterprise backup infrastructure. The day's total includes 10 critical and 100 high-priority CVEs, with critical counts down 58% from the prior day while high-priority volume held steady. CVE-2026-3611 in Honeywell IQ4x building controllers received a maximum CVSS 10.0 score, and CVE-2026-3059 and CVE-2026-3060 affect the SGLang AI framework at 9.8 each. Attack patterns span remote code execution and authentication bypass across enterprise backup, industrial control systems, and AI/ML infrastructure. Eleven CVEs have confirmed active exploitation, including vulnerabilities in Ivanti Endpoint Manager, VMware Aria Operations, and several legacy Apple and Hikvision flaws, while patch availability currently sits at 0%.

  • Veeam Backup & Replication faces five critical vulnerabilities (CVSS 9.1–9.9), requiring urgent review of all backup infrastructure
  • 10 critical CVEs disclosed, a 58% decrease from the prior day's 24 critical vulnerabilities
  • 100 high-priority CVEs reported, unchanged from the previous day's volume
  • Honeywell IQ4x building controllers received a maximum-severity CVSS 10.0 rating (CVE-2026-3611), affecting industrial control environments
  • Patch availability stands at 0% across all disclosed CVEs, limiting remediation to compensating controls and network segmentation
  • 11 actively exploited vulnerabilities include Ivanti EPM, VMware Aria Operations, Qualcomm chipsets, and legacy Apple and Hikvision flaws

Immediate action: Prioritize Veeam Backup & Replication environments for immediate risk assessment given five critical-severity flaws, and isolate Honeywell IQ4x building controllers from untrusted networks pending vendor guidance. With 0% patch availability across Friday's disclosures, implement compensating controls including network segmentation, enhanced monitoring, and access restrictions for all affected systems, particularly Ivanti EPM and VMware Aria Operations instances under active exploitation.

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.
