Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Information Disclosure: The HTTP client core failed to strip sensitive authentication headers (Authorization, Proxy-Authorization, Cookie) during cross-origin redirects, potentially exposing credentials to third-party domains. Developers should ensure the host validation logic successfully restricts header propagation on any redirect path.
Denial of Service: Unbounded caching of DateTimeFormatter instances and resource bundle caches keyed by attacker-controlled HTTP request headers (such as Locale tags and Accept-Language values) allows unauthenticated remote attackers to trigger heap memory exhaustion.
Auth Bypass: Permissive default CORS configurations (allowing credentials by default) exposed endpoints to unauthorized cross-origin resource sharing, violating the principle of secure defaults.
