Description

An improper neutralization of input during web page generation ('Cross-site Scripting') [CWE-79] vulnerability when using the XSSAPI.getValidHref() in Apache Sling XSS version 2.4.10 and prior may allow an attacker to perform a reflected cross-site scripting (XSS) attack in every feature using this method. In order to successfully attack an application, the attacker needs to be able to submit a value which is not correctly sanitized by that library. Upgrade to Apache Sling XSS >= 2.4.12
