Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Yesterday's vulnerability disclosures included 14 critical-severity CVEs, a 17% increase from the prior day's 12 critical issues. High-priority vulnerabilities rose significantly to 100, representing a 45% increase from 69 the previous day. Five actively exploited vulnerabilities were added to the KEV catalog, including CVE-2026-20805 affecting Microsoft Windows, CVE-2025-37164 in HPE OneView, and CVE-2025-8110 targeting Gogs. Critical vulnerabilities of note include CVE-2026-23524 (CVSS 9.8) in Laravel Reverb, CVE-2026-24061 (CVSS 9.8) in GNU Inetutils telnetd, and CVE-2021-47748 (CVSS 9.8) in Hasura GraphQL. Patch availability currently stands at 0%, requiring organizations to prioritize compensating controls and monitoring.

  • 14 critical CVEs disclosed, up 17% from prior day
  • 100 high-priority vulnerabilities, a 45% increase
  • 5 actively exploited: Microsoft Windows, HPE OneView, Gogs, Microsoft Office
  • 0% patch availability for newly disclosed vulnerabilities
  • Affected products include Laravel Reverb, GNU Inetutils, Hasura GraphQL, Academy LMS

Immediate action: Organizations using Microsoft Windows, HPE OneView, Gogs, and Microsoft Office should implement compensating controls immediately given confirmed active exploitation. With no patches currently available for yesterday's disclosures, focus on network segmentation, enhanced monitoring, and vendor advisory tracking for affected critical systems.

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.
