CVSS 7.5 HIGH
A flaw was found in js-yaml, a JavaScript YAML parser and dumper. A remote attacker could exploit this vulnerability by providing a specially crafted YAML document containing a chain of mappings with merge keys. This could cause the parser to consume excessive CPU resources, leading to a Denial of Service (DoS) for the affected system.
