CVE-2024-21526
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 · uneditedAll versions of the package speaker are vulnerable to Denial of Service (DoS) when providing unexpected input types to the channels property of the Speaker object makes it possible to reach an assert macro. Exploiting this vulnerability can lead to a process crash.
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 confidenceThe speaker npm package has a denial-of-service vulnerability in all versions where unexpected input types (non-integer or out-of-range values) passed to the channels property of the Speaker object triggers an assert macro, causing the process to crash.

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 checksWork through these to decide whether this CVE applies to you.
-
Check if speaker package is installedRun 'npm list speaker' in your project directory or inspect package.json for 'speaker' in dependenciesAffected if speaker is listed in dependencies or node_modules contains the speaker package
-
Identify installed speaker versionRun 'npm list speaker --depth=0' or check the version field in node_modules/speaker/package.jsonAffected if version is any version (all versions are affected per the CVE)
-
Find Speaker object usage with channels propertySearch your codebase for 'new Speaker' or 'Speaker(' and inspect where the channels property is set, for example: new Speaker({ channels: ... })Affected if Code instantiates Speaker object and sets the channels property without validation
-
Verify input validation on channels parameterInspect the code path that sets the channels property - look for type checking (typeof value === 'number'), integer validation (Number.isInteger()), and range validation (value >= 1 && value <= 2) before passing to SpeakerAffected if No validation exists and channels value could be a non-integer, negative number, zero, or greater than 2
You are affected if the speaker npm package is installed and your code passes unvalidated input to the Speaker channels property, allowing non-integer or out-of-range values to reach the internal assert macro.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation on the channels property to ensure only valid integer values within expected ranges (typically 1 or 2 for audio) are accepted, rejecting or sanitizing unexpected input types before they reach the assert macro.
