CVE-2025-40899 records a Unknown severity vulnerability in Stored Cross-Site Scripting (XSS) in Assets and Nodes in Guardian/CMC before 26.0.0. The current sources do not mark it as known exploited. The current feed maps Nozomi Networks/CMC (generic), Nozomi Networks/Guardian (generic), Siemens/RUGGEDCOM APE1808 (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

A Stored Cross-Site Scripting vulnerability was discovered in the Assets and Nodes functionality due to improper validation of an input parameter. An authenticated user with custom fields privileges can define a malicious custom field containing a JavaScript payload. When the victim views the Assets or Nodes pages, 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.
