Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Tuesday's vulnerability disclosure reflects elevated activity with 8 critical CVEs and 57 high-priority vulnerabilities, representing a 300% increase in critical vulnerabilities compared to Monday. Three severe SQL injection vulnerabilities in Blood Bank Management System (CVSS 10.0, 9.6, 9.6) and privilege escalation in Avast Antivirus (CVSS 9.0) highlight the most severe threats. Six CISA KEV vulnerabilities continue to require remediation across Samsung Mobile, Gladinet Triofox, Microsoft Windows, WatchGuard Firebox, and Google Chromium systems.

  • Eight critical vulnerabilities disclosed (CVSS 9.0+), a 300% increase from Monday's count of 2 critical CVEs
  • Fifty-seven high-priority vulnerabilities (CVSS 7.0-8.9), a 714% increase from Monday's 7 CVEs
  • Three Blood Bank Management System SQL injection flaws enable authentication bypass and data breach
  • Six CISA KEV vulnerabilities requiring remediation, unchanged from yesterday

Immediate action: Security teams should review the 8 critical vulnerabilities and assess organizational exposure to the 57 high-priority CVEs. Organizations should continue addressing the 6 CISA KEV 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.
