Description

The Slider Bootstrap Carousel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'category' and 'template' shortcode attributes in all versions up to and including 1.0.7. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. The plugin uses extract() on shortcode_atts() to parse attributes, then directly outputs the $category variable into multiple HTML attributes (id, data-target, href) on lines 38, 47, 109, and 113 without applying esc_attr(). Similarly, the $template attribute flows into a class attribute on line 93 without 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.
