description

@enspirit/elo versions before 1.0.1 can execute attacker-chosen JavaScript when an untrusted Elo expression is processed through its parser, CLI, or browser playground. An attacker needs control of the expression input; affected deployments may expose browser sessions or the runtime hosting the parser or CLI.

mitigation

Upgrade @enspirit/elo to version 1.0.1 or later. Until upgraded, do not process untrusted Elo expressions or expose affected parsing and CLI paths to attacker-controlled input.

fixed in 1.0.1
