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 if Citrix Workspace app for HTML5 is present
    Check installed applications or browser extensions for Citrix Workspace HTML5 component. On Windows, check Programs and Features or look for Citrix receiver HTML5 files in installation directories.
    Affected if Citrix Workspace app for HTML5 is installed on the system or as a browser extension
  2. Determine the installed version number
    Right-click the Citrix Workspace application, select About or Properties, or check the version displayed in the HTML5 session initialization screen. Compare the version to 2404.1.
    Affected if The installed version is lower than 2404.1 (for example, 2403.x or earlier)
  3. Verify HTML5 session capability is enabled
    Check Citrix Workspace settings or configuration files for HTML5/Citrix Receiver HTML5 enablement. Look for settings that control whether HTML5 sessions can be launched.
    Affected if HTML5 session launching is permitted in the workspace configuration
  4. Inspect redirect URL handling configuration
    Review Citrix Workspace HTML5 configuration files (typically in the workspace app data folder) for redirect URL validation settings. Check if custom redirect whitelists or allowed domains are defined.
    Affected if Redirect URL validation is not properly configured or uses overly permissive settings

A user is affected if they have Citrix Workspace app for HTML5 installed with a version lower than 2404.1 and have HTML5 session capabilities enabled, allowing potential exploitation of the open redirect vulnerability.
