🛡️ Sentinel: [HIGH] Fix Server-Side Request Forgery in webhooks

Adds validation to webhook URLs before attempting to deliver them to prevent
SSRF attacks targeting private IP ranges, local host, and cloud metadata endpoints.
Validates URL schema, hostname, and applies `is_private_ip()`. Also resolved ruff linting
errors. Tests have been expanded to ensure validation covers all cases.

-## 2024-05-24 - SSRF in WebDAV connection test
-**Vulnerability:** The `_test_webdav_connection` function had a custom SSRF check that failed to resolve DNS names, allowing attackers to bypass the check by providing a domain that resolves to an internal IP (e.g., `127.0.0.1`).
-**Learning:** DNS resolution is required for robust SSRF protection when validating URLs provided by users.
-**Prevention:** Use a centralized `is_private_ip` function (now in `app/utils/network.py`) that resolves the hostname to its IPs and checks if any are private.
-## 2026-03-22 - B310: urllib.request.urlopen replaced with httpx
-**Vulnerability:** The `_test_webdav_connection` function used `urllib.request.urlopen`, which natively supports dangerous schemes like `file://` or `ftp://` and follows redirects by default, potentially allowing SSRF bypasses or Local File Inclusion.
-**Learning:** `urllib.request` should be avoided for user-supplied URLs. Even when URL schemes are manually validated, `urllib`'s default redirect following behavior can bypass SSRF protections (e.g. redirecting to `127.0.0.1`).
-**Prevention:** Use a modern, safer HTTP client like `httpx` with `follow_redirects=False` when testing user-provided URLs.
+## 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.
