Descriptions

Neutralización incorrecta de la entrada durante la vulnerabilidad de generación de páginas web ('Cross site scripting') en smp7, wp.Insider Simple Membership permite XSS reflejado. Este problema afecta a Simple Membership: desde n/a hasta 4.3.8.

The Simple Membership plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via an unknown parameter in all versions up to 4.3.9 (exclusive) 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. This may be a duplicate of CVE-2023-6882.
