CVE-2026-54465

CVE-2026-54465 affects websocket-driver (Ruby) prior to version 0.8.1. A WebSocket server built on top of a TCP server via WebSocket::Driver.server() or a WebSocket client can trigger a memory exhaustion by sending an HTTP request/response with an unbounded, never-ending header list. The issue is...

CVE-2026-54463 websocket-driver: Memory exhaustion via abuse of protocol length headers

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.1, draft versions of the WebSocket protocol in websocket-driver include a length header that allows an arbitrarily large integer to be encoded as bytes with the high bit set, and a server or client can send an...

CVE-2026-54463

The CVE-2026-54463 issue affects the websocket-driver WebSocket protocol handler (prior to version 0.8.1). The root cause is a length header in draft WebSocket protocol frames that can encode an arbitrarily large integer, allowing a peer to send an indefinite sequence of 0x80+ bytes that are pars...

CVE-2026-54464 websocket-driver: Resource limit bypass via message compression

Impact If this library is used in tandem with the permessage-deflate extension, a WebSocket server or client can be made to accept messages that are larger than the configured maximum message size. This is because this limit is checked against the message frames' length headers, which give the si...
