|---|
| Description | Problem: send_push POSTed to whatever URL a client supplied in TaskPushNotificationConfig with no scheme/host/IP validation. A malicious client could point the server at http://127.0.0.1, http://x.x.x.x (cloud metadata), or any internal service (CWE-918). Go fixed this with an ssrfGuardedTransport + isBlockedIP; Python and JS fixed it via PR. Rust had no protection. |
