deepgram-webhooks-events

The code implements a plausible Deepgram asynchronous transcription workflow and contains no clear malicious or supply-chain attack behavior. The principal security concerns are optional webhook authentication, malformed-signature denial of service due to timingSafeEqual length handling, absent callback correlation and replay protection, lack of runtime payload validation, and possible abuse of user-controlled audio URLs by the external transcription service. These issues warrant remediation before production exposure, but the fragment does not indicate malware.
