Description

A vulnerability in Symfony PHP framework versions prior to 6.4.40, 7.4.12, and 8.0.12 allows unauthenticated POST requests to inject forged Twilio status payloads because the X-Twilio-Signature HMAC header is ignored by TwilioRequestParser::doParse(). This issue is fixed in the specified versions.

Technical Analysis

Symfony's TwilioRequestParser::doParse() method received the configured webhook secret but did not validate the X-Twilio-Signature HMAC header, allowing attackers to send unauthenticated POST requests with forged Twilio status payloads. This vulnerability affects multiple Symfony versions prior to 6.4.40, 7.4.12, and 8.0.12. The issue is resolved by validating the HMAC signature in these fixed versions.

Potential Impact

Attackers can send unauthenticated POST requests with forged Twilio status payloads, potentially leading to injection of false status information into applications relying on Symfony's TwilioRequestParser. This could affect application logic that depends on trusted Twilio webhook data.

Mitigation Recommendations

A fix is available in Symfony versions 6.4.40, 7.4.12, and 8.0.12. Users should upgrade to these or later versions to remediate the vulnerability. No additional mitigation steps are indicated.
