Summary

The UiChemy plugin for WordPress is vulnerable in all versions up to and including 5.3.0. Insufficient input sanitization and output escaping (CWE-79) allow stored cross-site scripting through the slot link URL setting. An authenticated attacker with Contributor access or above can inject arbitrary web scripts into pages. The injected javascript: payload runs when an Editor or Administrator clicks the crafted link while reviewing or previewing the post.

Description from the CNA

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.
