Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Yesterday's disclosures included 2 critical CVEs, a 92% decrease from the prior day's 26 critical vulnerabilities. High-priority vulnerabilities also declined significantly, with 39 CVEs compared to 100 the previous day, representing a 61% reduction. Ten actively exploited vulnerabilities remain on CISA's KEV catalog, affecting Microsoft Windows, Microsoft Office, Cisco Unified Communications Manager, HPE OneView, VMware vCenter Server, and Zimbra Collaboration Suite. Notable critical disclosures include CVE-2025-13374 (CVSS 9.8), an arbitrary file upload vulnerability in the Kalrav AI Agent WordPress plugin, and CVE-2026-24399 (CVSS 9.3) affecting ChatterMate. Patch availability stands at 0%, requiring organizations to implement compensating controls until vendor fixes are released.

  • 2 critical CVEs disclosed, down 92% from 26 the prior day
  • 39 high-priority CVEs, representing a 61% decrease from 100
  • 10 actively exploited vulnerabilities affecting Microsoft, Cisco, HPE, VMware, Gogs, Zimbra, Versa, and Vite
  • 0% patch availability for newly disclosed vulnerabilities
  • WordPress plugin (Kalrav AI Agent) and ChatterMate identified in critical severity disclosures

Immediate action: Organizations running Microsoft Windows, Cisco Unified Communications Manager, HPE OneView, VMware vCenter Server, or Zimbra should prioritize reviewing the actively exploited CVEs and implement available mitigations. With no patches currently available for newly disclosed critical vulnerabilities, focus on network segmentation and monitoring for exploitation attempts.

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.
