Descriptions

The LearnPress WordPress plugin before 4.2.5.5 does not sanitise and escape user input before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin.

El complemento LearnPress WordPress anterior a 4.2.5.5 no sanitiza ni escapa a la entrada del usuario antes de devolverla a la página, lo que genera cross site scripting reflejado que podría usarse contra usuarios con privilegios elevados, como el administrador.

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the add_internal_scripts_to_head function in all versions up to and including 4.2.5.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
