 **Vulnerability:** The `/process-url` endpoint used `httpx.AsyncClient(follow_redirects=True)` after validating the initial user-provided URL against SSRF protections. However, it did not validate the target URLs of any subsequent HTTP redirects, allowing an attacker to provide a safe URL that redirects to an internal/private IP, bypassing the security check.
 **Learning:** Initial URL validation is insufficient when the HTTP client is configured to follow redirects automatically. The client must be explicitly configured to validate every redirect target.
 **Prevention:** When using `httpx.AsyncClient(follow_redirects=True)` for user-provided URLs, always implement a redirect validator hook function (e.g., using `event_hooks={'response': [validate_redirect]}`) that resolves the `Location` header and passes it through the same SSRF validation logic before the redirect is followed.
+## 2026-03-27 - SyntaxError: keyword argument repeated in httpx event hooks
+**Vulnerability:** The `/process-url` endpoint in `app/api/url_upload.py` initialized `httpx.AsyncClient` with the `event_hooks` keyword argument twice. This caused a Python SyntaxError, effectively crashing the API endpoint and preventing any execution.
+**Learning:** Python does not allow duplicate keyword arguments. In scenarios where multiple hooks (like local and module-level SSRF interceptors) must be provided to a client, they must be merged into a single list value.
+**Prevention:** Combine multiple callables for the same event key into a single list, e.g., `event_hooks={"response": [hook1, hook2]}`.
