Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

This week's threat landscape delivered 109 critical vulnerabilities and 48 actively exploited CISA KEV entries, marking an intense period for security teams. D-Link surveillance infrastructure faces catastrophic authentication bypass exposures with federal deadlines expiring Monday. Friday brings fresh threats including Salesforce Tableau type confusion (CVE-2025-26496, CVSS 9.6) and Voltronic Power management systems with perfect CVSS 10 remote code execution. The week saw WordPress ecosystem under sustained attack, Microsoft Office vulnerabilities resurface in KEV catalog, and critical authentication bypasses across enterprise platforms.

  • 109 critical vulnerabilities disclosed this week - 33% above average
  • 48 CISA KEV entries with 3 federal deadlines expiring Monday August 25
  • Friday: Voltronic Power management RCE with CVSS 10 - public exploit available
  • Salesforce Tableau Server type confusion enables complete environment compromise
  • D-Link surveillance cameras face imminent KEV deadline - immediate isolation required
  • MallChat authentication bypass grants full API access without credentials

Immediate action: URGENT: D-Link DCS-2530L, DCS-2670L, and DNR-322L devices must be isolated or replaced by Monday federal deadline. Patch Voltronic Power ViewPower/PowerShield immediately. Review and secure all Tableau Server instances.

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.
