Recurring patterns

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

Auth Bypass: Recursive validation bypasses in ValidateStruct allow nested pointers and interface-typed fields to escape validation checks entirely, permitting malformed or malicious data to bypass structural application gates.

SSRF: Lenient URL schema parsing in IsURL permits malformed schemes to pass validation, which downstreams like Go's url.Parse may interpret incorrectly, facilitating SSRF or open redirect attacks.

Auth Bypass: Insufficent JWT structure validation in IsJWT allows syntactically invalid JSON or malformed base64url payloads to be accepted as valid tokens, potentially leading to authentication bypasses in consumer code.
