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
Improper permissions in the handler for the Custom URL Scheme in ToDesktop Builder v0.33.0 allows attackers with renderer-context access to invoke external protocol handlers without sufficient validation.

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 confidence

In ToDesktop Builder v0.33.0, the handler for Custom URL Schemes contains improper permission validation, allowing an attacker with renderer-context access to invoke external protocol handlers without sufficient authorization checks.

MitigationToDesktop should implement proper permission validation in the Custom URL Scheme handler to verify the origin and intent before allowing external protocol handler invocation, restricting which contexts can trigger external actions.

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. Check ToDesktop Builder version
    Run 'todesktop --version' in your terminal or check the version in your project's package.json dependencies
    Affected if The installed version is lower than 0.33.0
  2. Identify Custom URL Scheme configurations
    Examine your ToDesktop project configuration file (typically todesktop.config.js or similar) for any custom protocol handlers or urlSchemes entries
    Affected if Custom URL schemes are defined in your configuration and the version is below 0.33.0
  3. Verify renderer context access
    Determine if your application loads any third-party or untrusted content in the renderer process that could potentially invoke custom URL schemes
    Affected if Untrusted renderer content can load and your ToDesktop Builder version is below 0.33.0 with custom URL schemes configured
  4. Inspect protocol handler registration
    Check your built application manifest or electron configuration for registered protocol handlers (e.g., myapp://)
    Affected if Protocol handlers are registered in your app and the Builder version used to build it is below 0.33.0

You are affected if your ToDesktop Builder version is below 0.33.0 and your application uses Custom URL Schemes with potential untrusted renderer context access.
