The affected versions include all up to and including 1.52. No patch or remediation information is currently provided.

Successful exploitation can lead to execution of arbitrary scripts in the context of users viewing the affected pages, potentially allowing theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability.
