MLflow: Unauthenticated full-read SSRF in webhook delivery: _validate_webhook_url bypassed via unvalidated HTTP redirects (and DNS rebinding) (CVE-2026-64849)CVE-2026-64849 0 MLflow versions prior to 3.15.0 contain a critical vulnerability in the unauthenticated POST /api/2.0/mlflow/webhooks/{id}/test endpoint. The vulnerability arises because the _validate_webhook_url() function only validates the original URL, but the webhook delivery process follows HTTP redirects and re-resolves hostnames without enforcing address pinning. This allows attackers to bypass validation via unvalidated HTTP redirects and DNS rebinding, potentially accessing internal or cloud metadata services and retrieving response data. The issue is fixed in MLflow version 3.15.0. Join the discussion | GCVE Database | 08/21/2026, 05:51:48 UTC Added: 08/21/2026, 14:22:37 UTC |
