CVE-2026-59870 is a high-severity vulnerability in the js-yaml library used by nodeca. It causes excessive CPU consumption due to inefficient quadratic time complexity when processing the !!omap tag in YAML documents. This is caused by a linear duplicate-key scan on every insertion in the YAML11_SCHEMA support. The issue affects multiple versions of js-yaml prior to 5.2.1 and certain Ubuntu package versions. The vulnerability can lead to denial of service by exhausting CPU resources. A fix is available in version 5.2.1.

js-yaml is a JavaScript YAML parser and dumper. Prior to 3.15.1, 4.3.1, and 5.2.1, YAML11_SCHEMA support for the !!omap tag in src/tag/sequence/omap.ts uses omapTag.addItem() to perform a linear duplicate-key scan on every insertion, causing O(n^2) CPU consumption when yaml.load() parses a crafted ordered-map document. In v3 and v4, !!omap is active and exploitable by default. v5 doesn't use !!omap by default, and the chances of activating it are very low.This issue is fixed in 3.15.1, 4.3.1, and 5.2.1.
