Summary
The BWL Advanced FAQ Manager Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'baf_sbox' shortcode in all versions up to and including 1.1.1. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'sbox_id', 'sbox_class', 'placeholder', 'highlight_color', 'highlight_bg', and 'cont_ext_class'. These attributes are directly interpolated into HTML element attributes without any esc_attr() escaping in the baf_sbox() function. 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.
