The extension downloads audio files and plays them. It uses standard browser audio APIs, not any mechanism that could run code or commands. This matches its stated purpose of playing welcome and idle sounds.
Technical evidence
Scanner reason: JavaScript analysis matched static JavaScript security signal javascript.download-to-execution. The match applies to this repository.
Contextual assessment: The scanner correlates a network retrieval primitive (fetch at line 40) with an execution sink in the same representation. Examining the actual data flow: fetch retrieves audio file bytes as an ArrayBuffer, ctx.decodeAudioData parses audio data into an AudioBuffer, and source.start(0) plays the buffer through the Web Audio API graph (createBufferSource, createGain, connect, destination). None of these constitute dynamic code or command execution. There is no eval, Function constructor, import, or shell invocation. The fetched URLs are either relative paths resolved against the extension root (extensionRootUrl) or user-configured audio source strings from the settings UI, matching the project purpose of playing welcome and idle sounds. The decoded data is never written to persistent storage, transmitted elsewhere, or executed as code. This is expected media-loading behavior.
User-configured audio URLs are fetched for playback only
low risk · high confidence
Audio file paths are supplied by the user in the settings UI and only used to fetch and play sound. This is the intended functionality of the extension.
Technical assessment
getFullAudioUrl resolves user-configured source strings against the extension root URL, or passes through strings beginning with 'http' unchanged. These strings originate from extension_settings populated via the settings UI text inputs. The resulting URLs are consumed solely by fetch within loadAudioBuffer for audio decoding and playback, consistent with the documented feature set.
