Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Unbounded memory growth occurs in the WAMP TopicManager when empty topic storage containers are not explicitly removed from the lookup map upon connection closure. Attackers can exploit this by repeatedly opening and closing connections to exhaust server memory resources.
Auth Bypass: Falsy evaluation of an empty string passed as the HTTP Host parameter allows traffic to bypass Host header validation logic, potentially exposing the application to DNS rebinding or unauthorized connection hijacking.
