SCA: security update for websocket-driver (GHSA-ghhp-3qvg-889p)

medium Tenable Self-Hosted Container Security Plugin ID 446031

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 indefinite sequence of 0x80
 or higher bytes that the peer parses into an ever-growing Ruby integer. 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. (CVE-2026-54463)

Solution

Update the websocket-driver library and its related packages to version 0.8.1 or later.
