What it is

The SureDash – Community, Courses & Member Dashboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'draweropenverposition' Block/Shortcode Attribute in all versions up to, and including, 1.10.3 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 payload is stored inside the block-delimiter HTML comment's JSON, which wp_kses_post does not neutralize on save, and is only interpolated into the rendered style attribute at display time without esc_attr() escaping, allowing a double-quote to break out of the attribute and introduce arbitrary HTML event handlers.
