NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby4.0-rails-8.0 package and not the ruby4.0-rails-8.0 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.2, WebSocket::Driver.server() passes a malformed Host header to URI.parse in lib/websocket/http/request.rb without catching URI::InvalidURIError, allowing a remote client to crash a TCP-backed WebSocket server when the application does not catch the error from parse(). This issue is fixed in version 0.8.2.
