Kerentanan URL Redirection to Untrusted Site ('Open Redirect'). Skor CVSS 3.1 5.4 (Medium) menurut vulncheck.com.
h3 versions before 2.0.1-rc.18 contain an open redirect vulnerability in the redirectBack() utility that fails to sanitize protocol-relative paths in the Referer header pathname. Attackers can craft a same-origin URL with a double-slash path segment that passes origin validation but produces a Location header interpreted by browsers as a protocol-relative redirect to an external domain.
