Vulnerability details
The vulnerability allows a local privileged user to cause a denial of service through CPU exhaustion.
The vulnerability exists due to dependency on a vulnerable third-party component in the bundled js-yaml parser when parsing YAML translation files at the configured loadPath. A local privileged user can control a loaded YAML file containing repeated aliases in merge keys, merge-key chains, crafted !!omap structures, or empty merge sources to trigger excessive CPU consumption.
