Recurring patterns

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

Auth Bypass: A critical flaw in the caching validator incorrectly evaluated zero-size value nodes as empty schema objects. This skipped core validation logic entirely, effectively allowing invalid payloads to pass validation checks.

SSRF: Unrestricted schema resolution allowed remote JSON schema loading across arbitrary URI schemes. This exposed the system to local file disclosure and internal protocol handling vulnerabilities before being restricted to HTTP.

Server-Side Request Forgery: Validating IPv4 address formats directly via resolution methods triggered DNS lookups on unverified inputs, leading to potential blind SSRF vectors.
