Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: URL double-unescaping and platform-specific path separators on Windows consistently allowed attackers to escape the static directory root. Mitigation requires robust canonicalization and strict prefix validation.
Auth Bypass: Unescaped or encoded path separators allowed attackers to bypass path-based route middleware checks, granting unauthorized access to restricted static resources before the routing layer handled unescaping.
Auth Bypass: Shared and overwritten middleware slices across sub-routes within the same Group allowed registration flaws where routes silently bypassed expected middleware guards.
