CVE-2026-15084Network attack vector

Stored XSS via insufficient component markup sanitization

Published Jul 10, 2026 · Updated Jul 10, 2026

Stored XSS in Drupal UI Patterns 2.0.0 through 2.0.16 allows remote authenticated users to execute script via component markup. The component rendering path passes attacker-controlled markup without sufficient sanitization, so it is stored and later interpreted in a viewer's browser. Exploitation requires permission to create or update content rendered by UI Patterns and affects users who view that content.
