Descriptions

NVD
Wordfence

The Blog Designer WordPress plugin before 2.4.1 does not validate and escape one of its shortcode attributes, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attack.

The Blog Designer - Post and Widget plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcodes in versions up to, and including, 2.3 due to insufficient input sanitization and output escaping on user supplied attributes like 'design'. This makes it possible for authenticated attackers with contributor level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page
