Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected website, potentially leading to partial confidentiality, integrity, and availability impacts. This could result in actions such as session hijacking, defacement, or other malicious activities depending on the victim's privileges and interaction. However, exploitation requires user interaction and low privileges, which somewhat limits the risk.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
