Description
The WP Plugin Info Card plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'layout' and 'expiration' attributes of the wp-pic shortcode in all versions up to, and including, 6.3.5. This is due to insufficient input sanitization and output escaping on these values, which are placed into HTML attributes of cards loaded with AJAX. 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.
