No patch is available, but Siemens recommends disabling the Virtual Switch binding, using Softbus mode, and restricting multicast as immediate mitigations.
CISA Flags MikroTik API Login Flaw: Disable Remote Access or Risk Compromise
MikroTik RouterOS and Cloud Hosted Router API services lack protection against brute-force password guessing, CISA warns. No patch exists, so admins must disable the API when not needed, enforce VPN access, restrict source IPs, and use strong, unique passwords to prevent full router compromise.
Mendix's Hidden Account Leak: How a Documentation Gap Created a 9.1-Severity Access Control Flaw
Siemens disclosed CVE-2026-7891, a critical 9.1-severity flaw in all Mendix Runtime versions caused by a documentation gap that led developers to apply overly permissive access rules to the System.User entity. The platform's built-in access rules for System.User override any XPath constraints on its specializations, potentially exposing all user records — especially dangerous when anonymous access is enabled. Remediation requires auditing role-management settings, not applying a patch, and moving user-data restrictions from XPath to App Security configuration.
