Mira CVE-2026-66340

Consult CISA ICS Medical Advisory ICSMA-26-223-01 at https://www.cisa.gov/news-events/ics-medical-advisories/icsma-26-223-01 for vendor-specific patch guidance; patch available per vendor advisory, but no exact patched firmware or app version number was present in the available source data and fix version is not independently confirmed. As compensating controls pending patch deployment, operators should enforce strong, unique passwords for all Mira accounts to materially increase brute-force search space, and enable multi-factor authentication if the Mira platform supports it, as even weak rate limiting at the MFA layer would substantially raise attack cost. Organizations should configure alerting on anomalous authentication volume against the Mira cloud endpoints and consider restricting endpoint access to known IP ranges via network egress controls or firewall policy - note that IP restriction may conflict with mobile app usability for roaming users. A web application firewall with credential stuffing detection rules can throttle automated attempt volume at the perimeter, though this is a bypass-able control rather than a fix. The CSAF advisory at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsma-26-223-01.json may contain additional vendor-recommended mitigations.
