Descriptions

The Popup Builder WordPress plugin before 4.2.3 does not prevent simple visitors from updating existing popups, and injecting raw JavaScript in them, which could lead to Stored XSS attacks.

El complemento Popup Builder de WordPress anterior a 4.2.3 no impide que los visitantes simples actualicen las ventanas emergentes existentes e inyecten JavaScript sin formato en ellas, lo que podría provocar ataques XSS almacenados.

The Popup Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via popups in versions up to 4.2.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
