description:WordPress plugin Simpel Reserveren 3.5.2 and before contains a reflected cross-site scripting vulnerability which allows an attacker to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.
Successful exploitation of this vulnerability could allow an attacker to inject malicious scripts into web pages viewed by users, leading to potential data theft or unauthorized actions.
Upgrade to the latest version of the WordPress Simpel Reserveren plugin (>=3.5.3) or apply a patch provided by the vendor to fix the XSS vulnerability.
