CVE-2026-40490: Asynchttpclient Cross Domain Credential Leak
AsyncHttpClient instances unconditionally copy Realm credentials to arbitrary redirect targets without checking domain boundaries. This propagates plaintext credentials on cross-domain redirects or HTTPS-to-HTTP downgrades. To fix this, ensure the realm is stripped when crossing origin boundaries securely.
