Summary

Telnyx Webhook Replay Detection Bypass via Base64 Signature Re-encoding

Current Maintainer Triage

  • Status: narrow
  • Normalized severity: low
  • Assessment: Shipped v2026.3.28 replay hashing treated equivalent Telnyx Base64/Base64URL signatures as distinct requests, but signature verification still held, so lower to low.
