🚨 Severity: HIGH
💡 Vulnerability: Hardcoded secret salt (
"idsec_secret_salt") used in cryptographic HMAC signature generation in the/api/webhooks/test-processroute.🎯 Impact: Exposed secrets in source code allow attackers to forge valid webhook signatures, bypass integrity verification checks, or trigger unauthorized processing.
🔧 Fix: Retrieved the secret dynamically from
process.env.WEBHOOK_HMAC_SECRETand return an error if unconfigured.✅ Verification: Code review completed and type checks verified.
