The Report Builder component of the application stores user input directly in a web page and displays it to other users, which raised concerns about a possible Cross-Site Scripting (XSS) attack. Proper management of this functionality helps ensure a secure and seamless user experience. Although the user input is not validated in the report creation, these scripts are not executed when the report is run by end users. The script is executed when the report is modified through the report builder by a user with edit permissions.
The Report Builder is part of the WebConsole. The WebConsole package is currently end of life, and is no longer maintained. We strongly recommend against installing or using it in any production environment. However, if you choose to install it, for example, to access functionality like the Report Builder, it must be deployed within a fully isolated network that has no access to sensitive data or internet connectivity. This is a critical security precaution, as the retired package may contain unpatched vulnerabilities and is no longer supported with updates or fixes.
Impact
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.
CVE-2025-12776 has a CVSS score of 5.4 (Low). The vector is network-reachable, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-12776? CVE-2025-12776 is a low-severity cross-site scripting (XSS) vulnerability. No fixed version is listed yet. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- How severe is CVE-2025-12776? CVE-2025-12776 has a CVSS score of 5.4 (Low). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Is there a fix for CVE-2025-12776? No fixed version is listed for CVE-2025-12776 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is CVE-2025-12776 exploitable, and should I be worried? Whether CVE-2025-12776 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-12776 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
