CVE-2025-5198 — Redhat Advanced Cluster Security security vulnerability

Medium CVSS 5.4

A flaw was found in Stackrox, where it is vulnerable to Cross-site scripting (XSS) if the script code is included in a small subset of table cells. The only known potential exploit is if the script is included in the name of a Kubernetes “Role” object* that is applied to a secured cluster. This object can be used by a user with access to the cluster or through a compromised third-party product.

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
