symfony/twilio-notifier is vulnerable to Missing Authentication
65

This Affects:
symfony/twilio-notifierTL;DR
TwilioRequestParser receives the configured webhook secret but does not verify the X-Twilio-Signature header. A forged POST to an application webhook endpoint is decoded and accepted as a Twilio callback. Pre-fix applications can process fake delivery, failure, or status events. The fix verifies the Twilio HMAC signature before parsing the webhook payload.
