WordPress Vulnerabilities

WP 6.6 - 7.1.3 - Contributor+ Stored XSS via Script Module Data Shadowing

Description

WordPress reads JSON configuration from a DOM element by id in some cases without constraining it to the intended script element, which could allow users with contributor-level access and above to shadow that data and perform Stored Cross-Site Scripting attacks. This also affects the Gutenberg plugin.
