CISA Warns of Actively Exploited MikroTik RouterOS Vulnerabilities

CISA has added two MikroTik RouterOS vulnerabilities to its Known Exploited Vulnerabilities Catalog due to evidence of active exploitation. The flaws include CVE-2026-67277, a missing authentication vulnerability for a critical function, and CVE-2026-86060, an improper neutralization of argument delimiters in a command.

Why it matters

CISA notes that these vulnerabilities serve as frequent attack vectors for malicious cyber actors. When present on publicly exposed assets, such vulnerabilities can grant attackers total control over the affected system post-exploitation.

What it means for your practice

Practices and their IT providers should determine if MikroTik RouterOS equipment is in use on their networks and prioritize rapid remediation. In accordance with CISA guidance, organizations should also check whether systems were compromised before applying updates.

Orthanc DICOM Server Vulnerable to Denial-of-Service Flaw

A vulnerability in Orthanc DICOM Server versions prior to 1.13.0 allows an authenticated remote attacker to trigger a heap out-of-bounds write. The issue stems from an integer overflow in pitch and buffer-size computation when decoding an attacker-supplied PNG or JPEG image. Exploitation crashes the Orthanc process, causing a denial-of-service condition.

Information blocking expectations keep tightening

The federal information blocking rules require that patients and their designated recipients get electronic access to their records without unnecessary delay, and enforcement attention has continued to grow rather than fade.
