Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Untrusted binders can spoof their element source to bypass restrictions. Guice must enforce strong validation flags on the path trust chain of elements.
Auth Bypass: Exposing public constructors for binding implementations allows external untrusted packages to forge internal dependency bindings. Access must be strictly restricted to package-private.
Path Traversal: Servlet and filter routing patterns can be bypassed using unnormalized path traversal sequences. Path normalization must occur before pattern matching.
