CVE-2026-55247: Incomplete File Scheme Url Validation
URL validation only blacklists the 'file:' protocol via startswith(). This does not protect against other dangerous schemes such as 'javascript:', 'data:', or SSRF vectors. Use an explicit scheme allowlist (e.g., http/https) and parse URLs using urllib.parse.urlsplit or urlparse.
