Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Saturday's security landscape reveals 22 critical vulnerabilities, a 24% decrease from Friday's 29 critical disclosures. High-priority vulnerabilities held steady at 100 issues requiring attention. Five actively exploited vulnerabilities demand immediate focus, including CVE-2025-14847 affecting MongoDB, CVE-2026-20805 targeting Microsoft Windows, and CVE-2025-37164 impacting HPE OneView. Canon printer firmware vulnerabilities dominate today's critical disclosures with multiple buffer overflow issues (CVE-2025-14231, CVE-2025-14232, CVE-2025-14234, CVE-2025-14235, CVE-2025-14236, CVE-2025-14237) affecting Small Office Multifunction Printers. Current patch availability stands at 0%, requiring organizations to implement compensating controls until vendor remediation becomes available.

  • 22 critical vulnerabilities disclosed, down 24% from prior day's 29
  • 100 high-priority vulnerabilities, unchanged from previous day
  • 5 actively exploited CVEs affecting MongoDB, Microsoft Windows, HPE OneView, and Gogs
  • 0% patch availability requires compensating controls and enhanced monitoring
  • Canon printer firmware affected by 7 buffer overflow vulnerabilities requiring network segmentation

Immediate action: Organizations using MongoDB, Microsoft Windows, HPE OneView, Gogs, or Canon multifunction printers should prioritize threat hunting and implement network segmentation for affected systems. With no patches currently available, deploy compensating controls including enhanced logging, access restrictions, and intrusion detection signatures for the actively exploited 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.
