CVE-2025-36746 identifies a Cross-Site Scripting (XSS) vulnerability classified under CWE-79 in the SolarEdge Monitoring platform, a SaaS product used for monitoring solar energy systems. The flaw arises from improper neutralization of input during web page generation, specifically allowing authenticated users to inject malicious JavaScript payloads into report names. When a victim user attempts to delete a report containing such a payload, the script executes in their browser context. This can lead to various attacks including session hijacking, credential theft, or unauthorized actions performed with the victim's privileges. The vulnerability requires that the attacker be authenticated to the platform and that the victim interacts with the malicious report deletion interface, which limits the attack surface. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required beyond authentication, and user interaction needed. Confidentiality, integrity, and availability impacts are low to limited. No patches or known exploits are currently documented, but the vulnerability is publicly disclosed and should be addressed promptly. The SolarEdge Monitoring platform is widely used in managing solar assets, making this vulnerability relevant to organizations relying on this infrastructure for energy management and operational continuity.

For European organizations, the impact of this vulnerability centers on the potential compromise of user sessions and unauthorized actions within the SolarEdge Monitoring platform. Given the platform’s role in managing solar energy assets, exploitation could disrupt monitoring activities, lead to data leakage of operational reports, or enable attackers to manipulate report data. While the vulnerability does not directly affect the physical solar infrastructure, compromised monitoring could delay detection of operational issues or maintenance needs, indirectly impacting energy production and operational efficiency. Organizations with multiple users managing solar assets are at higher risk, especially if internal users can be tricked into interacting with maliciously crafted reports. The medium severity rating reflects the limited scope of exploitation due to authentication and user interaction requirements, but the strategic importance of solar energy management in Europe elevates the need for timely mitigation. Additionally, attackers could leverage this XSS flaw as a foothold for further attacks within the organization’s network or to pivot to other systems.

To mitigate CVE-2025-36746, organizations should implement the following specific measures: 1) Apply strict input validation and sanitization on all user-supplied data fields, particularly report names, to prevent injection of executable scripts. 2) Employ robust output encoding techniques when rendering user inputs in the web interface to neutralize any embedded scripts. 3) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context. 4) Enforce least privilege access controls to limit the number of users who can create or delete reports, reducing the attack surface. 5) Monitor user activities related to report management for unusual patterns or repeated failed attempts that could indicate exploitation attempts. 6) Engage with SolarEdge for updates or patches addressing this vulnerability and apply them promptly once available. 7) Educate users about the risks of interacting with untrusted content within the platform, emphasizing caution when deleting or managing reports. 8) Consider network segmentation and multi-factor authentication to further reduce the risk of unauthorized access to the monitoring platform.
