Severity Important	Advisory/CVECVE-2026-73643	Synopsis A flaw was found in js-yaml, a JavaScript YAML parser. A remote attacker could exploit this vulnerability by providing specially crafted YAML input containing nested flow collections. This can lead to exponential parsing time when the application processes untrusted input, consuming excessive CPU resources. This resource exhaustion can block the Node.js event loop and cause a Denial of Service (DoS) for the affected process.	Date
