CVE-2026-47212

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 6.4.40, 7.4.12, and 8.0.12, TwilioRequestParser::doParse() received the configured webhook secret but ignored the X-Twilio-Signature HMAC header, allowing unauthenticated POST requests to inject forged Twilio status payloads. This issue is fixed in versions 6.4.40, 7.4.12, and 8.0.12.
