Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Yesterday's disclosures included 9 critical-severity CVEs, a 200% increase from the prior day's 3. High-priority vulnerabilities also rose substantially to 66 from 26, representing a 154% increase. Eight actively exploited vulnerabilities were added to CISA's Known Exploited Vulnerabilities catalog, including issues affecting GeoServer, Google Chromium, Apple products, MongoDB, and ASUS Live Update. Notable critical vulnerabilities include CVE-2025-52691 (CVSS 10) enabling unauthenticated arbitrary file uploads, CVE-2025-68860 affecting Mobile Builder with authentication bypass, and CVE-2025-68897 involving code generation control issues. Patch availability stands at 0%, requiring organizations to prioritize compensating controls and monitoring.

  • 9 critical CVEs disclosed, up 200% from prior day's 3
  • 66 high-priority CVEs, a 154% increase from 26
  • 8 actively exploited vulnerabilities including GeoServer, Chromium, Apple, MongoDB, and ASUS
  • 0% patch availability for newly disclosed vulnerabilities
  • Multiple file upload vulnerabilities affecting MapSVG, WMPro, and BPMFlowWebkit systems

Immediate action: Organizations using GeoServer, Apple products, MongoDB, ASUS Live Update, Chromium, or Gladinet CentreStack should review KEV entries immediately. With no patches currently available for newly disclosed critical issues, implement network segmentation and enhanced monitoring for affected 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.
