CVE-2025-12776
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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 The WebConsole package is currently end of life, and is no longer maintained.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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Report Builder component of the end-of-life WebConsole stores user input directly into web pages without validation, creating a stored XSS vulnerability. While the malicious scripts do not execute when end users run reports, they DO execute when users with edit permissions modify the report through the Report Builder interface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Commvault installed versionRun 'commvault -version' or check the Commvault installation directory for version information, typically found in the installation logs or the 'Base' directoryAffected if Version falls within 11.36.0-11.36.68 or 11.32.0-11.32.112 ranges
-
Confirm WebConsole component is presentCheck if the WebConsole service is installed and running. This is typically accessible via port 80/443 on the Commvault serverAffected if WebConsole is installed and accessible on the network
-
Verify Report Builder interface accessCheck if the Report Builder component is accessible by logging into WebConsole and navigating to the Reports section, or check for Report Builder configuration filesAffected if Report Builder interface is available to users with edit permissions
-
Audit for existing reports created via Report BuilderReview the Commvault database or report storage location for reports that may have been created or modified using the Report Builder, as these could contain malicious payloadsAffected if Reports exist that were created or modified through the Report Builder interface by users with edit permissions
You are affected if your Commvault version is 11.36.0-11.36.68 or 11.32.0-11.32.112 AND the WebConsole with Report Builder is accessible to users with edit permissions who can modify reports.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataThe WebConsole is end-of-life and unmaintained - it should not be used in production. If already deployed, either decommission it entirely or deploy it within a fully isolated network with no access to sensitive data or internet connectivity.
