Incorrect Privilege Assignment in PrivateContent Leads to Privilege Escalation

Compliance Impact

The vulnerability allows unauthenticated attackers to escalate privileges and potentially gain full control of the website, which can lead to unauthorized access to sensitive data.

Such unauthorized access and privilege escalation can compromise the confidentiality, integrity, and availability of data, potentially violating compliance requirements under standards like GDPR and HIPAA that mandate strict access controls and protection of personal and health information.

Therefore, if exploited, this vulnerability could lead to non-compliance with these regulations due to failure to adequately protect sensitive data from unauthorized access.
