What it is

The yootheme WordPress theme before 5.0.35 does not prevent its bundled front-end framework from treating certain HTML attributes, which are permitted by wp_kses_post(), as markup, allowing users with the Author role to perform Stored Cross-Site Scripting attacks that execute in the browser of any user who views the affected post.
