Descriptions

The Welcart e-Commerce WordPress plugin before 2.8.9 does not validate and escapes one of its shortcode attributes, which could allow users with a role as low as a contributor to perform a Stored Cross-Site Scripting attack.

El complemento Welcart e-Commerce de WordPress anterior a 2.8.9 no valida ni escapa uno de sus atributos de código corto, lo que podría permitir a los usuarios con un rol tan bajo como colaborador realizar un ataque de cross-site scripting almacenado.

The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcodes in versions up to, and including, 2.8.8 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor level privileges and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
