07 Remediation
The fix applies HTML output encoding to the user-controlled label variable (lbl) before it is interpolated into the innerHTML string in both affected view templates. By wrapping the label with escapeHtml(), any HTML metacharacters in object names are neutralized, preventing injected markup from being interpreted as executable HTML or JavaScript in the viewer's browser.
