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 · unedited
An XSS issue was discovered in Thycotic Secret Server before 10.7 (issue 1 of 2).

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 · moderate confidence

Cross-Site Scripting (XSS) vulnerability in Thycotic Secret Server versions before 10.7 allows attackers to inject malicious scripts into web pages viewed by other users, potentially leading to session hijacking or credential theft.

MitigationUpgrade Thycotic Secret Server to version 10.7 or later. Apply input validation and output encoding to user-supplied data in affected components.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify Thycotic Secret Server version
    Log into the Secret Server web interface as an administrator. Navigate to Help > About or Admin > Configuration > General Settings to view the installed version number.
    Affected if The displayed version is below 10.7.000000 (for example, 10.6.x, 10.5.x, etc.)
  2. Verify web interface accessibility
    Confirm the Secret Server web interface is accessible to users. XSS vulnerabilities in web applications require the web interface to be reachable.
    Affected if The web interface is accessible and users can input data into web forms or view content rendered by the application
  3. Check for user input points in web application
    Review web pages in Secret Server that accept user-supplied input such as search fields, custom templates, folder names, secret naming, or notes fields.
    Affected if User-accessible input fields exist in the web interface that could accept and render unsanitized content back to users
  4. Confirm user roles and access
    Navigate to Admin > Users or Admin > Roles to determine if multiple user accounts with different privilege levels exist in the system.
    Affected if Multiple users or groups have access to view content created by others, enabling stored XSS propagation
  5. Review admin configuration for customizations
    Check Admin > Configuration for any enabled custom features, templates, or integrations that allow user-defined content to be displayed.
    Affected if Custom templates, workflows, or third-party integrations are enabled that handle user-supplied data without additional encoding

You are affected if your installed Thycotic Secret Server version is before 10.7.000000 and the web interface is accessible to multiple users who can input or view content that may not be properly sanitized.
