UiChemy <= 5.3.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Slot Link URL
Impact

Original source description
The UiChemy – Convert Figma, Prompts and AI Builds to Elementor, Gutenberg and Bricks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'actions[save_builder][data][elements][...][settings][slot_{N}_link][url]' parameter in all versions up to, and including, 5.3.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected javascript: payload fires on click rather than on page load, making exploitation contingent on a privileged user such as an Editor or Administrator clicking the attacker-crafted link while reviewing or previewing the Contributor's post.
