Published: 2025-01-27 · updated 2026-06-17
Weakness: CWE-79

Description

A flaw was found in the Red Hat Advanced Cluster Security (RHACS) portal. When rendering a table view in the portal, for example, on any of the /main/configmanagement/* endpoints, the front-end generates a DOM table-element (id="pdf-table"). This information is then populated with unsanitized data using innerHTML. An attacker with some control over the data rendered can trigger a cross-site scripting (XSS) vulnerability.
