The WP Table Builder – Drag & Drop Table Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'url' parameter in versions up to, and including, 2.1.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and higher, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation by lower-privileged users requires an administrator to explicitly allow those roles in plugin settings. While it is possible to assign subscriber-level roles with the ability to create tables, such privileges are usually assigned to the more appropriate contributor, author, or editor level roles.
