CyberRota Analysis
AI-GeneratedThe Media Library Assistant plugin for WordPress is susceptible to Stored Cross-Site Scripting (XSS) due to inadequate input sanitization and output escaping of the 'mla_link_href' parameter in the 'mla_gallery' shortcode. This vulnerability allows authenticated attackers with contributor-level access or higher to inject malicious scripts that execute when users visit affected pages. WordPress site administrators using this plugin should prioritize patching to mitigate potential exploitation risks.
Original NVD Description
The Media Library Assistant plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mla_gallery' shortcode in versions up to and including 3.35. This is due to insufficient input sanitization and output escaping on the mla_link_href parameter when mla_output is set to 'paginate_links', where the _paginate_links() function processes the value through mla_process_shortcode_parameter() and _replace_query_parameter() without proper URL escaping, then outputs it directly in href attributes without applying esc_url(). 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.
