Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: An integer overflow in the length of received websocket frames allows attackers to mount denial of service attacks against the HTTP server. This represents a critical data processing risk within the core library.
Auth Bypass: Allowing non-GET HTTP methods to initiate a WebSocket upgrade can lead to protocol validation bypasses. Explicitly enforcing the GET method during the handshake is critical to preventing unauthorized connection upgrades.
Reflected XSS: Using unsafe text/template rendering in example applications can expose users to Reflected Cross-Site Scripting (XSS). Replacing this with html/template ensures proper contextual output encoding.
