Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Thursday's security landscape presents 36 critical vulnerabilities with concerning supply chain risks from unmaintained third-party components. SAP NetWeaver continues facing severe authentication bypass threats (CVSS 9.9), while Microsoft HPC Pack deserialization flaws persist. Organizations struggle with historically low patch availability at 18%, creating significant remediation bottlenecks across enterprise environments.

  • ⚠️ Supply chain crisis: Multiple critical vulnerabilities from unmaintained third-party dependencies
  • 💼 SAP NetWeaver authentication bypass (CVSS 9.9) continues threatening enterprise ERP systems
  • 🔴 36 critical vulnerabilities maintain elevated threat levels from Wednesday's surge
  • 📉 Patch availability hits critical low at 18% - organizations forced to deploy compensating controls
  • 💾 SQL injection vulnerabilities resurge across multiple web applications and databases

Immediate action: Audit third-party dependencies immediately for unmaintained components. Deploy application firewalls and network segmentation while awaiting patches for the 82% of unpatched vulnerabilities.

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.
