CVE-2025-5198Network attack vector

Stored XSS via unsanitized PDF table cells

Published May 27, 2025 · Updated Feb 27, 2026

Stored XSS in StackRox and Red Hat Advanced Cluster Security allows attackers to run scripts when a user exports affected table data to PDF. The PDF table builder in ui/apps/platform/src/utils/pdfUtils.js assigns flattened column values, including Kubernetes Role names, to a cell's innerHTML without sanitizing them. A Role bearing the payload must reach a secured cluster, and a user must export the affected view; the script then runs in that user's rendering context.
