js-yaml: js-yaml: Denial of Service via crafted YAML documents

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 o...

UBUNTU-CVE-2026-59869

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...

UBUNTU-CVE-2026-59868

js-yaml is a JavaScript YAML parser and dumper. From 5.0.0 before 5.2.0, when merge keys are enabled, 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...

CVE-2026-59870

CVE-2026-59870 affects js-yaml prior to 5.2.1. The YAML11_SCHEMA’s handling of the !!omap tag in omap.ts performs a linear duplicate-key scan on each insertion, causing O(n^2) CPU usage when yaml.load() parses crafted ordered-map documents. Red Hat and NVD entries confirm this results in CPU-inte...

PT-2026-56489

Name of the Vulnerable Software and Affected Versions js-yaml versions 5.0.0 through 5.1.x Description When merge keys are enabled, the parser can consume quadratic CPU time while processing a document. This occurs when a chain of mappings uses merge keys where each mapping merges the previous on...
