webpack-dev-server: webpack-dev-server: Information disclosure and denial of service via improper proxy configuration

A flaw was found in webpack-dev-server. When a user configures a proxy with a broad context, such as '/', and enables WebSocket ws: true forwarding, the development server's own Hot Module Replacement HMR WebSocket can be intercepted. This interception leads to the leakage of the browser's cookie...

undici: undici: Denial of Service due to unbounded memory growth via WebSocket frames

A flaw was found in undici. A malicious WebSocket server can exploit this by streaming numerous small or empty continuation frames. This can bypass per-frame and cumulative-size validation, leading to unbounded memory growth in the client process. The primary consequence is memory exhaustion,...

ws: ws: Denial of Service via memory exhaustion from small WebSocket fragments

A flaw was found in ws, an open source WebSocket client and server. A remote attacker can exploit this memory exhaustion vulnerability by sending a high volume of exceptionally small fragments and data chunks. This action forces the affected component to allocate and hold structural wrappers that...
