Archived Security Snapshot

Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Yesterday's disclosures reveal 12 critical vulnerabilities concentrated across WordPress plugins, HP products, and NPM packages, alongside continued active exploitation of Google Chrome and Apple platforms. Critical CVE volume dropped 60% from the prior day (12 vs. 30), while 100 high-priority vulnerabilities held steady. Notable critical findings include CVE-2026-25366 (CVSS 9.9, HP code execution), CVE-2026-4484 (CVSS 9.8, WordPress), and CVE-2026-26830 (CVSS 9.8, pdf-image NPM package command injection). Attack patterns are dominated by remote code execution across web content management systems and supply chain risks in NPM dependencies. No patches are currently available for yesterday's disclosures, and 10 vulnerabilities have confirmed active exploitation targeting Google Chromium, Apple products, and Zimbra.

  • HP, WordPress plugins, and NPM packages account for the majority of critical-severity disclosures
  • 12 critical CVEs disclosed, a 60% decrease from the prior day's 30
  • 100 high-priority CVEs, unchanged from the previous day
  • Remote code execution dominates attack patterns, with supply chain risks in pdf-image and node-tesseract-ocr NPM packages (CVSS 9.8)
  • 0% patch availability across all disclosed vulnerabilities — no vendor fixes released yet
  • 10 actively exploited vulnerabilities include Google Chromium V8, Apple multiple products, and Langflow

Immediate action: Prioritize monitoring Google Chromium, Apple iOS/iPadOS, Zimbra, and Wing FTP Server environments where active exploitation is confirmed, and apply any out-of-band mitigations available from vendors. Review WordPress plugin deployments — especially JetFormBuilder, Green Downloads, and TotalPoll Lite — and consider disabling vulnerable plugins until patches are released, as no fixes are currently available for any of yesterday's critical disclosures.

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.
