Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Yesterday's disclosure activity revealed 29 critical-severity vulnerabilities, a 480% increase from the prior day's 5 critical CVEs. High-priority vulnerabilities remained steady at 100, unchanged from the previous period. Five actively exploited vulnerabilities require attention, including CVE-2025-14847 affecting MongoDB Server, CVE-2025-37164 in HPE OneView, and CVE-2026-20805 targeting Microsoft Windows. The critical disclosures are dominated by Canon printer vulnerabilities (CVE-2025-14231 through CVE-2025-14237) affecting Small Office Multifunction Printers through various buffer overflow conditions. Patch availability currently stands at 0%, requiring organizations to implement compensating controls until vendor fixes become available.

  • 29 critical CVEs disclosed (480% increase from prior day's 5)
  • 100 high-priority CVEs identified (unchanged from prior period)
  • 5 actively exploited vulnerabilities including MongoDB, HPE OneView, Gogs, and Microsoft Windows
  • 0% patch availability for disclosed vulnerabilities
  • Canon Small Office Multifunction Printers affected by multiple buffer overflow vulnerabilities

Immediate action: Organizations using Canon multifunction printers, MongoDB Server, HPE OneView, Gogs, or Microsoft Windows should prioritize assessment of exposure to actively exploited vulnerabilities. With no patches currently available, implement network segmentation and access controls as compensating measures until vendor remediation is released.

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.
