What to check
- Applies to
- The 4 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- CISA lists CVE-2025-67038, CVE-2026-34908, CVE-2026-34909, and CVE-2026-34910 as exploited in the wild.
CISA has updated its Known Exploited Vulnerabilities Catalog with four new entries based on evidence of active exploitation in the wild. The additions include CVE-2025-67038, a code injection vulnerability in Lantronix EDS5000 devices, and three flaws in Ubiquiti UniFi OS: CVE-2026-34908 (improper access control), CVE-2026-34909 (path traversal), and CVE-2026-34910 (improper input validation).
The KEV Catalog supports CISA's Binding Operational Directive 26-04, which mandates Federal Civilian Executive Branch agencies to prioritize rapid remediation of high-risk vulnerabilities on publicly exposed assets that could grant total control post-exploitation. While the directive applies only to federal agencies, CISA recommends all organizations adopt risk-based vulnerability management practices and prioritize patching KEV-listed vulnerabilities.
Organizations using affected Lantronix or Ubiquiti products should apply available patches immediately and assess whether systems were compromised prior to remediation. CISA continues to accept nominations for additional KEV entries through its online submission form.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
