NVD Description

Note: Versions mentioned in the description apply only to the upstream tileserver-gl-fips package and not the tileserver-gl-fips package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

js-yaml is a JavaScript YAML parser and dumper. Prior to 4.2.0, a crafted YAML document can trigger algorithmic CPU exhaustion in js-yaml merge-key processing (<<) by repeating the same alias many times in a merge sequence. This causes quadratic parse-time behavior relative to input size and can block a Node.js worker/event loop for seconds with a relatively small payload (tens of KB), resulting in denial of service. The issue is in merge handling inside lib/loader.js. This vulnerability is fixed in 4.2.0.
