All OpenShift Container Platform 4.17 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.redhat.com/en/documentation/openshift_container_platform/4.17/html-single/updating_clusters/index#updating-cluster-cli.

shell-quote prior to 1.8.5 finalizes parsed tokens in parse() using Array.prototype.concat as a reduce accumulator, which reallocates and copies the entire growing array on every iteration. As a result parse() runs in O(n^2) time relative to the number of input tokens. An attacker who can supply an attacker-controlled string to any code path that calls parse() (no shell metacharacters are required; plain space-separated words suffice) can block the single-threaded Node.js event loop for an extended period with a small input, resulting in a denial of service. There is no code execution or data disclosure; impact is to availability only. Fixed in 1.8.5.

This security update for python-pytest-html addresses vulnerabilities in its dependencies shell-quote and js-yaml. The shell-quote vulnerability (CVE-2026-13311) involves inefficient input parsing that can lead to denial of service. The js-yaml vulnerability (CVE-2026-53550) involves quadratic complexity when processing crafted YAML documents, potentially causing CPU exhaustion. Both issues are fixed by updating the respective dependencies.

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.

This update includes the following RPMs: yarnpkg: * yarnpkg-1.22.22-18.1.hum1 (aarch64, x86_64) * yarnpkg-1.22.22-18.1.hum1.src (src)
