NVD · unedited
Unrestricted Upload of File with Dangerous Type vulnerability in Tumult Inc. Tumult Hype Animations.This issue affects Tumult Hype Animations: from n/a through 1.9.12.

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

An unrestricted file upload vulnerability in Tumult Hype Animations versions up to 1.9.12 allows attackers to upload dangerous file types (likely executable scripts, HTML, or other malicious content) without proper validation. This can lead to remote code execution if the uploaded files are stored in a web-accessible location and subsequently accessed.

MitigationImplement strict file type validation (both by extension and content/magic bytes), store uploads outside the web root or with non-executable permissions, and apply proper access controls. Update to the patched version once released.

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. Confirm Tumult Hype Animations is installed
    Look for Tumult Hype in /Applications folder on macOS, or check system-installed applications list using 'ls /Applications' or 'system_profiler SPApplicationsDataType'
    Affected if The application is present on the system
  2. Identify the installed version number
    Open Tumult Hype and navigate to 'Tumult Hype' > 'About Tumult Hype' from the menu bar, or right-click the app in Applications and select 'Get Info' to view the version
    Affected if The version is 1.9.12 or earlier (any version up to and including 1.9.12)
  3. Check if the web export or hosting feature is enabled
    Look for web export options in Tumult Hype preferences or project settings - check if 'Publish to Web' or similar hosting features are configured
    Affected if Web export or any web hosting functionality is enabled and configured
  4. Locate where exported animation files are stored
    Check the export destination folder - common locations include the project folder, a designated web exports folder, or a local web server document root
    Affected if Exported files are being saved to a web-accessible directory (such as /Library/WebServer/Documents, ~/Sites, or any directory served by a web server)
  5. Verify uploaded/exported file types are unrestricted
    Review Tumult Hype export settings or any custom upload scripts - check if there is file type validation configured for exports
    Affected if There is no extension or content-type validation configured, allowing potentially dangerous file types (HTML, JS, executable scripts) to be exported

You are affected if Tumult Hype Animations version 1.9.12 or earlier is installed AND web export/hosting is enabled with uploads stored in a web-accessible location without file type restrictions.
