Research Description
Spectra Gutenberg Blocks (v2.19.21) is an advanced extension for the WordPress block editor (Gutenberg), providing over 30 customizable blocks, layout tools, templates, and UI components for building modern websites without coding. Designed for websites running on WordPress, Spectra enhances the native editor instead of replacing it, allowing users to build feature-rich pages while maintaining compatibility with WordPress core architecture. With over 1+ million active installations, Spectra operates at a critical layer of content rendering and user interaction. Due to its complexity and broad functionality (including dynamic content, forms, popups, and frontend rendering), a comprehensive security audit was conducted.
