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
toggle-array is a package designed to enables a property on the object at the specified index, while disabling the property on all other objects. A Prototype Pollution vulnerability in the enable and disable function of toggle-array v1.0.1 and before allows attackers to inject properties on Object.prototype via supplying a crafted payload, causing denial of service (DoS) as the minimum consequence.

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

The toggle-array package versions v1.0.1 and earlier contain a Prototype Pollution vulnerability in the enable and disable functions. These functions allow attackers to inject arbitrary properties into Object.prototype by using crafted payloadsinstead of valid array indices (e.g., using __proto__ or constructor as keys), enabling denial of service and potentially more severe attacks.

MitigationUpgrade to a patched version of toggle-array (v1.0.2 or later) that implements input validation to reject prototype-injecting property names as array indices.

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. Locate toggle-array in your project dependencies
    Search your package.json files and node_modules directory for the toggle-array package. Run `npm list toggle-array` or `grep -r "toggle-array" package.json` in your project root.
    Affected if toggle-array is listed as a direct or transitive dependency
  2. Identify the installed version
    Run `npm list toggle-array` or check the version field in node_modules/toggle-array/package.json. Compare this version to the affected range (v1.0.1 and earlier).
    Affected if The installed version is 1.0.1 or any earlier version (e.g., 1.0.0, 0.x.x)
  3. Inspect code using enable or disable functions
    Search your codebase for calls to toggleArray.enable() or toggleArray.disable() methods. Review how the index/key argument is obtained (e.g., from user input, API parameters, or external data).
    Affected if The enable or disable functions accept index values from untrusted sources without validation
  4. Verify input validation on array index parameters
    Examine the enable and disable function implementations in node_modules/toggle-array/index.js (or the actual source file). Check whether the code validates that the provided key is a valid array index (integer >= 0) and rejects special property names.
    Affected if The code does not validate that keys are valid array indices and would accept __proto__, constructor, or other prototype properties

You are affected if toggle-array version 1.0.1 or earlier is installed AND your code passes unvalidated user-controlled input to the enable or disable functions as array indices.
