telnyx-vercel-sms

No evidence of malware or intentional data theft is present. The code sends user-provided SMS messages to `api[.]telnyx[.]com` using `TELNYX_API_KEY` and logs inbound phone numbers and message text. The main security concern is that the send route lacks implemented authentication, allowing public callers to incur prepaid SMS charges; webhook deduplication is also not implemented. Severity is moderate if deployed publicly without access controls; relevant paths are `/api/send` and `/api/telnyx/inbound`.
