There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - js-yaml is a JavaScript YAML parser and dumper. Prior to 4.2.0 and 3.15.0, 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 and
    3.15.0. (CVE-2026-53550)

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21448-1 advisory.
