CVE-2024-50689Network attack vector

Unauthenticated data exposure via unchecked object references

Published Feb 26, 2025 · Updated Mar 4, 2025

Authorization bypass in Sungrow iSolarCloud before October 31, 2024 allows remote attackers to read and modify organizational data. The orgService API uses attacker-controlled object references without enforcing authorization for the referenced organization, exposing records and settings outside the permitted scope. Unauthenticated network access is sufficient, with impacts bounded to sensitive business-data exposure, organization-wide setting changes, and service disruption.
