Stored XSS in Nozomi Alerted Nodes Dashboard
CVE-2025-40894 4.4 - Medium - March 04, 2026

A Stored HTML Injection vulnerability was discovered in the Alerted Nodes Dashboard functionality due to improper validation on an input parameter. A malicious authenticated user with the required privileges could edit a node label to inject HTML tags. If the system is configured to use the Alerted Nodes Dashboard, and alerts are reported for the affected node, then the injected HTML may render in the browser of a victim user interacting with it, enabling phishing and possibly open redirect attacks. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.

XSS

Path Traversal in Arc Import Allows Authenticated File Write
CVE-2025-40898 8.1 - High - December 18, 2025

A path traversal vulnerability was discovered in the Import Arc data archive functionality due to insufficient validation of the input file. An authenticated user with limited privileges, by uploading a specifically-crafted Arc data archive, can potentially write arbitrary files in arbitrary paths, altering the device configuration and/or affecting its availability.

Directory traversal

Stored HTML Injection in Asset List via Network Packets
CVE-2025-40893 6.1 - Medium - December 18, 2025

A Stored HTML Injection vulnerability was discovered in the Asset List functionality due to improper validation of network traffic data. An unauthenticated attacker can send specially crafted network packets to inject HTML tags into asset attributes. When a victim views the affected assets in the Asset List (and similar functions), the injected HTML renders in their browser, enabling phishing and possibly open redirect attacks. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.

XSS

Stored XSS in Reports of Unknown Web App
CVE-2025-40892 8.9 - High - December 18, 2025

A Stored Cross-Site Scripting vulnerability was discovered in the Reports functionality due to improper validation of an input parameter. An authenticated user with report privileges can define a malicious report containing a JavaScript payload, or a victim can be socially engineered to import a malicious report template. When the victim views or imports the report, the XSS executes in their browser context, allowing the attacker to perform unauthorized actions as the victim, such as modify application data, disrupt application availability, and access limited sensitive information.

XSS

Stored HTML Injection in Time Machine Snapshot Diff via Network Packet Injection
CVE-2025-40891 4.7 - Medium - December 18, 2025

A Stored HTML Injection vulnerability was discovered in the Time Machine Snapshot Diff functionality due to improper validation of network traffic data. An unauthenticated attacker can send specially crafted network packets at two different times to inject HTML tags into asset attributes across two snapshots. Exploitation requires a victim to use the Time Machine Snapshot Diff feature on those specific snapshots and perform specific GUI actions, at which point the injected HTML renders in their browser, enabling phishing and open redirect attacks. Full XSS exploitation is prevented by input validation and Content Security Policy. Attack complexity is high due to multiple required conditions.

XSS

Grafana Stored XSS in Dashboard (CVE-2025-40890)
CVE-2025-40890 7.9 - High - November 25, 2025

A Stored Cross-Site Scripting vulnerability was discovered in the Dashboards functionality due to improper validation of an input parameter. An authenticated low-privilege user can craft a malicious dashboard containing a JavaScript payload and share it with victim users, or a victim can be socially engineered to import a malicious dashboard template. When the victim views or imports the dashboard, the XSS executes in their browser context, allowing the attacker to perform unauthorized actions as the victim, such as modify application data, disrupt application availability, and access limited sensitive information.

XSS

Access Control Bypass in Guardian/CMC Reports Lets Auth Users Alter SMTP Settings
CVE-2024-4465 5 - Medium - September 11, 2024

An access control vulnerability was discovered in the Reports section due to a specific access restriction not being properly enforced for users with limited privileges. If a logged-in user with reporting privileges learns how to create a specific application request, they might be able to make limited changes to the reporting configuration. This could result in a partial loss of data integrity. In Guardian/CMC instances with a reporting configuration, there could be limited Denial of Service (DoS) impacts, as the reports may not reach their intended destination, and there could also be limited information disclosure impacts. Furthermore, modifying the destination SMTP server for the reports could lead to the compromise of external credentials, as they might be sent to an unauthorized server. This could expand the scope of the attack.
