CVE-2026-4984

Descripción

The Twilio integration webhook handler accepts any POST request without validating Twilio-s -X-Twilio-Signature-. When processing media messages, it fetches user-controlled URLs (-MediaUrlN- parameters) using HTTP requests that include the integration-s Twilio credentials in the -Authorization- header. An attacker can forge a webhook payload pointing to their own server and receive the victim-s -accountSID- and -authToken- in plaintext (base64-encoded Basic Auth), leading to full compromise of the Twilio account.
