Descriptions

The User Avatar WordPress plugin before 1.2.2 does not properly sanitize and escape certain of its shortcodes attributes, which could allow relatively low-privileged users like contributors to conduct Stored XSS attacks.

El complemento User Avatar de WordPress anterior a 1.2.2 no sanitiza ni escapa adecuadamente a algunos de sus atributos de shortcodes, lo que podría permitir a usuarios con privilegios relativamente bajos, como los contribuyentes, realizar ataques XSS almacenados.

The User Avatar – Reloaded plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in versions up to, and including, 1.2.1 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
