Descriptions

The Spectra WordPress plugin before 1.15.0 does not sanitize user input as it reaches its style HTML attribute, allowing contributors to conduct stored XSS attacks via the plugin's Gutenberg blocks.

The Spectra – WordPress Gutenberg Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.14.11 due to insufficient sanitizing of input in Gutenberg blocks. This makes it possible for contributors, or higher privileged users, to inject arbitrary web scripts that execute in a victim's browser.
