The Islamic Database plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'islamicDB-roqya' shortcode in versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping on user-supplied 'width' and 'height' shortcode attributes within the islamicDB_sc_quran_qari_roqya() function, which are concatenated directly into HTML iframe attribute values. 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.
