Critical vulnerabilities, curated daily for security professionals

Archived Security Brief

Friday's vulnerability disclosures reveal 12 critical flaws concentrated across HP enterprise management systems, WordPress plugins, and LG mail security appliances. Critical CVE volume dropped 29% from Thursday's 17 to 12, while the 100 high-priority disclosures held steady. CVE-2026-31843 and CVE-2026-37345 (both CVSS 9.8) target HP payment and vehicle management platforms, while CVE-2026-6350 (CVSS 9.8) exposes LG MailGates and MailAudit to remote exploitation. Remote code execution and SQL injection patterns dominate the critical tier, with WordPress plugin vulnerabilities accounting for three of the top ten. No vendor patches are currently available for any disclosed CVE, and 9 vulnerabilities across Microsoft, Adobe, and Apache products have confirmed active exploitation.

  • HP enterprise platforms hit with 3 critical flaws (CVSS 9.1–9.8) across payment, parking, and payroll systems
  • Critical CVEs fell to 12, down 29% from Thursday's 17 disclosures
  • High-priority volume unchanged at 100 CVEs, maintaining elevated baseline
  • WordPress plugin RCE vulnerabilities (CVE-2026-4880, CVE-2026-3596, CVE-2026-6443) all scored CVSS 9.8
  • Patch availability at 0% — no fixes released for any of today's disclosed vulnerabilities
  • 9 actively exploited CVEs spanning Microsoft Exchange, SharePoint, Windows, Adobe Acrobat, and Apache ActiveMQ

Immediate action: Prioritize compensating controls for HP enterprise management systems, WordPress installations, and LG MailGates/MailAudit deployments where no patches exist. Organizations running Microsoft Exchange Server, SharePoint, and Adobe Acrobat should verify mitigations against the 9 actively exploited vulnerabilities, several of which target legacy flaws dating back to 2009.

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.
