Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Uncaught panics within status update goroutines and request processors, triggered by client disconnections, historically allowed remote attackers to crash the entire proxy service. Developers must enforce panic recovery wrappers around all goroutines executing proxy actions.
HTTP Request Smuggling: Improper synchronization of the Request.ContentLength field when modifying or forwarding HTTP bodies allowed for request desynchronization. Outbound proxy calls must explicitly propagate and override Content-Length headers rather than appending to them.
Auth Bypass: Missing early return statements after sending error responses in proxy handlers allowed control flow to continue executing downstream logic with invalid or unauthenticated state, bypassing intended security boundaries.
