A flaw was found in js-yaml, a JavaScript YAML (YAML Ain't Markup Language) parser. An attacker could exploit this by providing a specially crafted YAML ordered-map document. This could lead to excessive CPU consumption, resulting in a denial of service (DoS) for applications processing the malicious YAML input.
