Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Monday's vulnerability landscape centers on Digiwin EasyFlow .NET and industrial control systems, with two CVSS 9.8 flaws in Digiwin products and a critical issue affecting SD-330AC and AMC Manager devices. The brief includes 3 critical vulnerabilities (down 57% from 7) and 22 high-priority CVEs (down 52% from 46), reflecting a quieter disclosure cycle. Key critical entries include CVE-2026-5963 and CVE-2026-5964 affecting Digiwin EasyFlow .NET, alongside CVE-2026-32956 impacting SD-330AC and AMC Manager processing. Business application platforms and industrial control systems dominate today's attack surface, with 9 CVEs showing confirmed active exploitation across Microsoft, Adobe, and Apache products. No patches are currently available for the disclosed critical vulnerabilities, warranting defensive monitoring and compensating controls until fixes are released.

  • Digiwin EasyFlow .NET affected by two CVSS 9.8 vulnerabilities requiring immediate attention from enterprise users
  • Critical CVEs down 57% from prior day (3 vs 7), signaling reduced but still significant disclosure volume
  • High-priority CVEs down 52% from prior day (22 vs 46) across enterprise and industrial products
  • Industrial control systems impacted via CVE-2026-32956 affecting SD-330AC and AMC Manager processing
  • Patch availability at 0% for today's critical disclosures, requiring compensating controls and monitoring
  • 9 CVEs under active exploitation spanning Microsoft Exchange, SharePoint, Windows, Adobe Acrobat, and Apache ActiveMQ

Immediate action: Prioritize asset inventory and network isolation for Digiwin EasyFlow .NET deployments and SD-330AC/AMC Manager industrial devices pending vendor patches. Organizations running Microsoft Exchange, SharePoint, Windows, Adobe Acrobat, or Apache ActiveMQ should verify current patch levels given confirmed exploitation of the 9 KEV entries. No patches are available for today's critical CVEs, so apply network segmentation and enhanced monitoring until fixes are published.

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.
