Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Deadlocks during the proxy Stop sequence lock the structure indefinitely while waiting on internal channels. Developers should ensure mutex locks are released before blocking operations on channels like Tomb.
Auth Bypass: The admin API is vulnerable to cross-origin execution and DNS rebinding if browser-initiated requests are not restricted. Ensuring robust user-agent blocklisting or CORS policies is critical.
Denial of Service: Improper connection teardown leads to lingering network connections, leaking file descriptors and memory. Active tracking and removal of terminated connections are necessary.
