GHSA-ghhp-3qvg-889p: websocket-driver: Memory exhaustion via abuse of protocol length headersCVE-2026-54463 0 A vulnerability in websocket-driver prior to version 0.8.1 allows an attacker to cause memory exhaustion by abusing the protocol's length header parsing. The issue arises because the WebSocket draft protocol frame format permits encoding an arbitrarily large integer via a sequence of bytes with the high bit set. By sending a crafted sequence of such bytes, a peer can be forced to parse an ever-growing integer, causing unbounded memory consumption in the Ruby process. This can lead to the host process running out of memory and potentially crashing or becoming unresponsive. The vulnerability has been patched in version 0.8.1. No known workarounds exist.
