Compliance Impact

The vulnerability allows attackers with low-level access to escalate their privileges and potentially gain full control of the website. This could lead to unauthorized access to sensitive data, which may impact compliance with standards and regulations such as GDPR and HIPAA that require strict access controls and protection of personal and health information.
