The affected versions include all versions up to 6.8. There is no indication of an available patch or vendor advisory at this time.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of users viewing the affected web pages, potentially leading to information disclosure, modification of content, or disruption of service. The impact is rated medium with limited confidentiality, integrity, and availability effects. No known active exploitation has been reported.
