CVE-2026-54463Source published Source updated
websocket-driver is a WebSocket protocol handler with pluggable I/O. This can make a WebSocket connection consume an unbounded amount of memory and lead to the host process running out of memory. This issue is fixed in version 0.8.1. A remote attacker could exploit a vulnerability in how draft versions of the WebSocket protocol handle length headers. By sending an indefinite sequence of specially crafted bytes, an attacker can cause the affected component to consume an unbounded amount of memory.
