Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Concurrent access to request states (headers, URLs, and bodies) across parallel backend calls or shadow dispatch loops frequently triggers data races and fatal panics. This requires mandatory cloning of requests and headers prior to spawning goroutines.
Security Misconfiguration: Improper handling of Gin framework defaults overrides or clears critical trusted proxy configurations and client IP headers, leading to potential IP spoofing and bypass of downstream rate-limiting or authorization guards.
Path Traversal: Improperly sanitized routing parameters allow attackers to introduce URL-encoded path characters or special parameter sequences to escape intended route definitions, triggering routing bypass or path traversal.
