Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

SSRF: Multiple fixes target host-confusion between fast-uri and native URL parser, enabling SSRF/redirect bypass via malformed authority introducers or literal backslashes.

Host Confusion / SSRF: Host canonicalization after resolution was missing, allowing Unicode/IDN confusion that could bypass host-based access controls.

SSRF: Percent-encoded authority delimiters could alter the parsed host after unescape, enabling authority spoofing.
