Compliance Impact

CVE-2026-25023 involves exposure of sensitive data to unauthorized users, which can impact compliance with data protection standards such as GDPR and HIPAA. These regulations require that sensitive personal and health information be adequately protected from unauthorized access. The vulnerability allows unauthenticated attackers to retrieve sensitive information that should be restricted, potentially leading to violations of confidentiality and data protection requirements.

Although the severity is rated as low (CVSS 5.3), any exposure of sensitive data can increase the risk of non-compliance with these standards, as they mandate strict controls on data access and protection. Organizations using the affected plugin should update to version 2.1.1 or later to mitigate this risk and maintain compliance.
