Hi,
The following vulnerability was published for node-js-yaml.
CVE-2026-59869[0]:
| js-yaml is a JavaScript YAML parser and dumper. From 3.0.0 before
| 3.15.0 and from 4.0.0 before 4.3.0, js-yaml can spend quadratic CPU
| time parsing a document whose size grows only linearly when a chain
| of mappings uses merge keys where each mapping merges the previous
| one. This issue is fixed in versions 3.15.0 and 4.3.0.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
