Security vulnerabilities and automated fixes for websocket issues

Python-SocketIO versions prior to 5.16.2 contained a critical vulnerability where binary attachments could accumulate without bounds, allowing attackers to exhaust server memory and trigger a denial of service. This vulnerability has been patched through a dependency upgrade that implements proper resource limits on attachment handling.
A high-severity vulnerability (CVE-2026-48802) in python-engineio 4.12.2 allowed attackers to exhaust system resources through unbound thread allocation, leading to denial of service. The fix upgrades the dependency to version 4.13.2, which implements thread pool limits to prevent resource exhaustion attacks against real-time WebSocket applications.
A critical vulnerability (CVE-2026-54466) in websocket-driver versions prior to 0.7.5 allows attackers to corrupt WebSocket messages by manipulating protocol length headers. This can lead to data integrity issues, denial of service, or potentially arbitrary code execution in affected Node.js applications. The fix involves upgrading the websocket-driver dependency to version 0.7.5.
A medium-severity vulnerability was discovered in a JavaScript streaming application where insecure WebSocket (ws://) connections were being used instead of secure WebSocket (wss://) connections. This security gap could expose sensitive data to man-in-the-middle attacks, allowing attackers to intercept and manipulate real-time communication between clients and servers.
