Upgrade whatsapp-api-js to version 4.0.3 or higher.
Overview
whatsapp-api-js is an A TypeScript server agnostic Whatsapp's Official API framework
Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature via the verifyRequestSignature due to the failure in validating the message's signature. An attacker can bypass access controls by manipulating the signature verification process.
Workaround
It's possible to check the payload validation using the WhatsAppAPI.verifyRequestSignature and expect false when the signature is valid.
function doPost(payload, header_signature) {
if (whatsapp.verifyRequestSignature(payload.toString(), header_signature) {
throw 403;
}
// Now the payload is correctly verified
whatsapp.post(payload);
}
