Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Yesterday's disclosures revealed 28 critical CVEs, a 100% increase from the prior day's 14 critical vulnerabilities. High-priority CVEs held steady at 100, matching the previous day's count. Nine actively exploited vulnerabilities were added to the KEV catalog, an 80% increase, affecting Microsoft Office (CVE-2009-0556), HPE OneView (CVE-2025-37164), Gogs (CVE-2025-8110), Microsoft Windows (CVE-2026-20805), and Zimbra Collaboration Suite (CVE-2025-68645). Critical vulnerabilities include Azure Resource Manager privilege escalation (CVE-2026-24304, CVSS 9.9), Azure Front Door access control bypass (CVE-2026-24306, CVSS 9.8), and Langflow remote code execution flaws (CVE-2026-0768, CVE-2026-0769, both CVSS 9.8). Patch availability currently stands at 0%, requiring organizations to implement compensating controls while monitoring for vendor updates.

  • 28 critical CVEs disclosed, 100% increase from prior day's 14
  • 100 high-priority CVEs, unchanged from previous day
  • 9 actively exploited CVEs affecting Microsoft, HPE, Gogs, and Zimbra
  • 0% patch availability requires compensating controls
  • Azure services, Langflow, MetaGPT, and Tenda devices among affected systems

Immediate action: Organizations using Microsoft Azure services, Langflow, MetaGPT, HPE OneView, Gogs, and Zimbra should prioritize risk assessment and implement network segmentation or access restrictions. With no patches currently available, focus on monitoring vendor advisories and applying updates immediately upon release.

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.
