CVE-2026-33076: Python Path Traversal Fstring Host Param Unvalidated
A function builds a filesystem path (or path-like string later passed to open()/os.system()) by f-string interpolating a host/IP/server-style parameter without first validating it (e.g. via an `is_ip_or_dns`-style check that reassigns the parameter, or a pydantic IPvAnyAddress/DomainName typed parameter).
