Executive Summary
In December 2025, the SolisCloud Monitoring Platform, widely used across the global energy sector, was found to have a critical API vulnerability that allowed authorization bypass via a user-controlled key. This flaw, tracked as CVE-2025-13932, permitted any authenticated user to manipulate API requests and access detailed plant data belonging to other customers by altering the plant_id parameter. The vulnerability, present in both API v1 and v2, exposed sensitive operational information and highlighted a significant risk of data leakage in cloud-hosted critical infrastructure platforms. No mitigation had been released by SolisCloud at the time of public disclosure.
This incident underscores the heightened threat of insecure APIs in industrial control systems, coinciding with a broader increase in supply chain risks and attacks targeting energy infrastructure. Regulatory bodies are likely to intensify scrutiny, given the global deployment and criticality of such platforms in the energy sector.
Why This Matters Now
Exploitable API vulnerabilities in critical cloud platforms create urgent risk, especially as attackers increasingly target energy infrastructure for espionage or disruption. Prompt attention is needed because unmitigated access control flaws can be abused remotely, scaling impact rapidly and evading traditional perimeter defenses.
Attack Path Analysis
The attacker remotely exploited a broken access control vulnerability in the SolisCloud Monitoring Platform API, bypassing authorization via a manipulated API request. After initial access, the attacker could enumerate plant IDs or broaden access scope but did not necessarily escalate privileges due to the insufficient access control. With access to sensitive data, they could laterally query additional resources tied to other plant_ids. Through persistent API requests, the attacker maintained control of the compromised session, enabling further data exfiltration. Information was exfiltrated via authorized but manipulated API calls, exposing sensitive energy infrastructure details. While no destructive activity was reported, loss of confidentiality and potential business exposure reflect the main impact.

Recommended Actions
Key Takeaways & Next Steps
- • Enforce identity-based and least privilege segmentation at the API, workload, and network levels to restrict lateral access in multi-tenant cloud applications.
- • Implement east-west traffic detection and continuous anomaly response to rapidly identify and contain unauthorized resource access or enumeration within cloud environments.
- • Apply egress policy enforcement and encryption to monitor and block suspicious data flows, minimizing opportunities for data exfiltration via API abuse.
- • Gain centralized, multicloud visibility to detect and investigate unauthorized access events, bridging gaps between application, network, and identity layers.
- • Regularly assess and update cloud security controls, prioritizing Zero Trust strategies, microsegmentation, and continuous validation of authentication and authorization mechanisms.
