CVE-2025-66077 is a vulnerability identified in the wpWax Legal Pages WordPress plugin, affecting all versions up to and including 1.4.6. The core issue is a missing authorization check, meaning that the plugin fails to properly verify whether a user has the necessary permissions before allowing access to certain functionalities or data. This results from incorrectly configured access control security levels within the plugin's code. Attackers exploiting this vulnerability could bypass intended restrictions, potentially accessing or modifying legal page content or related administrative settings without proper credentials. Since the plugin is used to manage legal pages—such as privacy policies, terms of service, and cookie notices—unauthorized changes could lead to misinformation or compliance risks. The vulnerability was published on November 21, 2025, with no CVSS score assigned and no known exploits in the wild at the time of reporting. The absence of a patch link suggests that a fix may not yet be available, emphasizing the need for immediate attention by site administrators. The vulnerability's exploitation does not require user interaction but does depend on the attacker having some level of access to the WordPress environment, although the exact privilege level needed is not specified. Given the plugin's role and the nature of the flaw, the risk includes unauthorized disclosure or alteration of legal content, which can have legal and reputational consequences for affected organizations.

For European organizations, the impact of CVE-2025-66077 can be significant, particularly for those relying on WordPress sites to display legally mandated information such as privacy policies and terms of service. Unauthorized modification or access to these pages can lead to non-compliance with GDPR and other regional data protection laws, potentially resulting in regulatory fines and legal challenges. Additionally, altered legal content can erode customer trust and damage brand reputation. Organizations in sectors with strict compliance requirements—such as finance, healthcare, and e-commerce—are especially vulnerable. The vulnerability could also be leveraged as a foothold for further attacks if attackers gain administrative access through this flaw. Since the plugin is widely used in WordPress environments, which are popular across Europe, the scope of affected systems could be broad. The lack of a patch increases the window of exposure, making proactive mitigation critical. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability is public knowledge.

To mitigate CVE-2025-66077, European organizations should first identify all WordPress installations using the wpWax Legal Pages plugin and verify their versions. Until an official patch is released, administrators should restrict access to the WordPress backend to trusted IP addresses and enforce strong authentication mechanisms such as multi-factor authentication (MFA). Implementing a Web Application Firewall (WAF) with custom rules to detect and block unauthorized access attempts targeting the plugin’s endpoints can provide an additional layer of defense. Regularly auditing user roles and permissions to ensure least privilege principles are enforced will reduce the risk of exploitation. Monitoring logs for unusual activity related to legal page management is advisable. Organizations should subscribe to vendor and security mailing lists to receive timely updates and apply patches immediately upon release. If feasible, temporarily disabling or replacing the plugin with alternative solutions that do not have this vulnerability can be considered. Finally, conducting penetration testing focused on access control mechanisms can help identify residual risks.
