CVE-2026-107194
CriticalCVSS 9.2Summary
Sungrow iSolarCloud before 2026 allows authentication bypass and account takeover via "login_type":"5" in a login request, potentially leading to "local blackouts on the whole continent" in Europe. An email address for the user_account property is required; however, a user can view the email address associated with their parent organization.
Risk Assessment
Authentication bypass and account takeover in an energy management system could allow an attacker to manipulate energy infrastructure, potentially leading to severe disruptions in power supply, even blackouts.
Recommendation
Upgrade iSolarCloud to a version after 2026 that fixes this vulnerability. Enforce strong authentication and monitor login logs for unusual requests.
