Compliance Impact

The vulnerability allows attackers with low-privileged access to escalate their permissions and potentially gain full control of the website. This privilege escalation can lead to unauthorized access to sensitive data and systems.

Such unauthorized access and control can result in violations of common standards and regulations like GDPR and HIPAA, which require strict controls over data access and protection of personal and health information.

Therefore, if exploited, this vulnerability could compromise compliance by enabling attackers to bypass authentication and authorization controls, leading to potential data breaches and regulatory non-compliance.
