Descriptions

The Web Push Notifications WordPress plugin before 4.35.0 does not prevent visitors on the site from changing some of the plugin options, some of which may be used to conduct Stored XSS attacks.

El complemento Web Push Notifications de WordPress anterior a 4.35.0 no impide que los visitantes del sitio cambien algunas de las opciones del complemento, algunas de las cuales pueden usarse para realizar ataques XSS Almacenados.

The Web Push Notifications – Webpushr plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the wpp_save_settings function in all versions up to, and including, 4.34.0. This makes it possible for unauthenticated attackers to modify plugin options and inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
