Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

This disclosure includes 29 critical-severity vulnerabilities (CVSS 9.0+), a 32% increase from yesterday's 22 critical CVEs. High-priority vulnerabilities remain steady at 100 entries with no change from the previous day. Twelve actively exploited vulnerabilities require attention, including CVE-2025-14733 affecting WatchGuard Firebox, CVE-2022-37055 targeting D-Link Routers, CVE-2025-6218 in RARLAB WinRAR, and CVE-2025-62221 impacting Microsoft Windows. Notable critical disclosures include multiple SQL injection and filename control vulnerabilities (CVE-2025-68506, CVE-2025-68519, CVE-2025-68590) and legacy issues in Smartwares HOME easy and devolo dLAN products. Current patch availability stands at 0%, requiring organizations to implement compensating controls.

  • 29 critical CVEs disclosed, up 32% from yesterday's 22 critical vulnerabilities
  • 100 high-priority CVEs remain consistent with previous day totals
  • 12 actively exploited vulnerabilities including WatchGuard, D-Link, Microsoft Windows, and Google Chromium
  • 0% patch availability requires immediate compensating control deployment
  • Affected systems include WinRAR, GeoServer, Apple products, ASUS Live Update, and Gladinet CentreStack

Immediate action: Prioritize review of the 12 actively exploited vulnerabilities, particularly those affecting perimeter devices (WatchGuard Firebox, D-Link Routers, Array Networks) and widely deployed software (WinRAR, Microsoft Windows, Google Chromium). With no patches currently available, implement network segmentation, enhanced monitoring, and access restrictions for affected systems. Given the holiday period, ensure security operations coverage and incident response procedures are in place.

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.
