-## 2025-02-14 - SSRF vulnerability in webhook outgoing requests
-**Vulnerability:** Found an SSRF vulnerability where outgoing webhook requests could hit private IPs or metadata endpoints (e.g. 169.254.169.254).
-**Learning:** This existed because the `url` parameter provided for webhooks (`app/utils/webhook.py` and `app/utils/user_notification.py`) was not being checked before being passed to `requests.post()` or `httpx.post()`.
-**Prevention:** Make sure to always validate URL scheme and hostname with `is_private_ip()` and block known cloud metadata endpoints before doing outgoing network requests based on dynamic values.
+## 2025-05-18 - [SSRF Bypass via DNS Resolution Failure]
+**Vulnerability:** The `is_private_ip` function in `app/utils/network.py` failed open (returned `False`) when a hostname could not be resolved (`socket.gaierror`).
+**Learning:** This fail-open pattern was originally added to allow external domains in tests, but in production, it created a severe SSRF risk. An attacker could bypass SSRF protections by providing a URL that fails to resolve during the security check but resolves later (DNS rebinding), or by exploiting internal routing behaviors via unresolvable addresses.
+**Prevention:** Always fail securely in network authorization functions. If a domain cannot be resolved to verify its safety, the request must be blocked (`return True` / default-deny). Tests should mock DNS resolution correctly instead of compromising production security logic.
