Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Yesterday's disclosures contained zero critical-severity CVEs, a significant decrease from the prior day's two critical vulnerabilities. High-priority vulnerabilities dropped 60% to 21 entries compared to 53 previously. Four actively exploited vulnerabilities were added to the KEV catalog, including CVE-2009-0556 affecting Microsoft Office, CVE-2025-37164 in HPE OneView, CVE-2025-8110 targeting Gogs, and CVE-2026-20805 impacting Microsoft Windows. All four KEV entries carry CVSS scores of 9.5, indicating severe impact potential despite the absence of newly disclosed critical CVEs. Patch availability stands at 0%, indicating these vulnerabilities currently lack vendor-supplied fixes.

  • Zero critical CVEs disclosed, down from 2 the prior day (-100%)
  • 21 high-priority vulnerabilities, reduced from 53 (-60%)
  • 4 actively exploited vulnerabilities added to KEV catalog
  • 0% patch availability across disclosed vulnerabilities
  • Affected vendors include Microsoft, HPE, and Gogs

Immediate action: Organizations running Microsoft Office, Microsoft Windows, HPE OneView, or Gogs should prioritize reviewing these actively exploited vulnerabilities for potential exposure. With no patches currently available, implement compensating controls such as network segmentation, access restrictions, and enhanced monitoring for affected systems.

How to read this brief

CVSS score (e.g. 9.1) β€” severity from 0–10. Red marks critical (9+), orange high (7–8.9).

Exploitability β€” how hard the flaw is to attack, read from the CVSS vector:

  • Network / Adjacent / Local / Physical β€” how close an attacker must get. Network means reachable over the internet.
  • No / Low / High privileges β€” the access they need first. No privileges means no login required.
  • No interaction / User interaction β€” 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 β€” β€œNetwork Β· No privileges Β· No interaction” is the worst case: hit from anywhere, no credentials, no victim action.

Actively exploited β€” confirmed under attack in the wild (CISA’s Known Exploited Vulnerabilities catalog). Prioritize these regardless of score.

EPSS Β· Nth percentile β€” FIRST.org’s estimated chance a flaw is exploited within 30 days. We flag it only in the top 10% β€” a statistical signal it’s unusually likely to be targeted, separate from whether attacks are confirmed.
