CVE-2025-40892 Dec 18, 14:15 HIGH This Week

Stored cross-site scripting in Nozomi Networks CMC and Guardian allows authenticated users with report privileges to inject malicious JavaScript payloads into report definitions. When victims view or import these weaponized reports, the XSS executes in their browser context, enabling attackers to modify application data, disrupt availability, and access sensitive information. The vulnerability requires low-privilege authentication and user interaction (CVSS:4.0 score 7.1, PR:L/UI:P), with high integrity and availability impacts but limited confidentiality exposure. No public exploit identified at time of analysis, though the attack technique is well-understood and straightforward given the stored XSS nature.
