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 Flipsnack installation version
    Locate the Flipsnack installation in your environment and check the version information. This may be found in application metadata, a version file, or the main application interface.
    Affected if The installed version is dated 18/03/2024 or earlier (unpatched versions).
  2. Locate reader.gz.js file
    Search for the reader.gz.js file within the Flipsnack installation directory. Common locations include the root application folder or a scripts/js subdirectory.
    Affected if The reader.gz.js file exists in the deployment.
  3. Check file accessibility
    Verify that the reader.gz.js file is accessible via web requests or local file system access without authentication. Attempt to retrieve the file contents.
    Affected if The file can be accessed without authentication or privileged access.
  4. Examine file contents for sensitive data
    Review the contents of reader.gz.js to identify if it contains sensitive information such as credentials, API keys, internal paths, or configuration data that should not be exposed.
    Affected if The file contains credentials, API keys, internal system information, or other sensitive data that is exposed.
