Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Saturday's disclosure cycle reports 13 critical CVEs, a 48% decrease from Friday's 25 critical vulnerabilities. High-priority issues declined 9% to 91 CVEs, while actively exploited vulnerabilities increased 6% to 17 KEV entries. Notable KEV additions include CVE-2025-59718 affecting Fortinet products, CVE-2025-48633 and CVE-2025-48572 targeting Android Framework, CVE-2025-40602 in SonicWall SMA1000 appliances, and CVE-2025-20393 impacting Cisco products. Critical vulnerabilities include CVE-2025-13329 (arbitrary file upload in File Uploader for WooCommerce), CVE-2025-68613 (CVSS 9.9), and CVE-2025-14964 affecting TOTOLINK devices. Patch availability stands at 0%, requiring compensating controls across all disclosed vulnerabilities.

  • 13 critical CVEs disclosed, down 48% from Friday's 25
  • 91 high-priority vulnerabilities, a 9% decrease from 100
  • 17 actively exploited CVEs including Fortinet, Android Framework, SonicWall SMA1000, and Cisco products
  • 0% patch availability requires immediate compensating controls
  • WordPress plugins (File Uploader for WooCommerce, Flex Store Users) and network appliances (TOTOLINK, D-Link) heavily represented

Immediate action: Prioritize network segmentation and access controls for Fortinet, SonicWall, and Cisco devices listed in KEV entries. Implement web application firewall rules to block exploitation attempts against WordPress plugin vulnerabilities. Weekend security teams should monitor for exploitation activity against Android Framework and WinRAR vulnerabilities while awaiting vendor patches.

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.
