Technical details

The SureDash plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via shortcode attributes in versions up to and including 1.10.0. The root cause is insufficient input sanitization and output escaping within the plugin's shortcode handling logic, specifically in components like the user profile shortcode. An authenticated attacker with contributor-level permissions or higher can exploit this by injecting arbitrary web scripts into a page via a shortcode. These scripts are then stored and executed in the context of any user's browser who visits the compromised page. This vulnerability is tracked as CWE-79 and has been addressed in subsequent updates.
