Descriptions

The Keyword Meta WordPress plugin through 3.0 does not sanitise of escape its settings before outputting them back in the page after they are saved, allowing for Cross-Site Scripting issues. Furthermore, it is also lacking any CSRF check, allowing attacker to make a logged in high privilege user save arbitrary setting via a CSRF attack.

El plugin Keyword Meta WordPress versiones hasta 3.0, no sanea ni escapa sus ajustes antes de devolverlos a la página después de ser guardados, permitiendo problemas de tipo Cross-Site Scripting. Además, también carece de cualquier comprobación de tipo CSRF, que permite a un atacante hacer que un usuario con privilegios elevados guarde una configuración arbitraria por medio de un ataque CSRF.
