CVE-2025-64294 identifies a Missing Authorization vulnerability (CWE-862) in the d3wp WP Snow Effect WordPress plugin, versions up to 1.1.15. This vulnerability arises because certain plugin functionalities are accessible without proper enforcement of access control lists (ACLs), allowing unauthenticated remote attackers to invoke these functions. The CVSS 3.1 base score is 5.3 (medium), reflecting that the attack vector is network-based with low attack complexity, no privileges or user interaction required, and impacts integrity but not confidentiality or availability. The vulnerability could allow attackers to manipulate plugin behavior or settings, potentially leading to unauthorized changes in website appearance or functionality, which could be leveraged for further attacks or to degrade user trust. No patches or exploit code are currently available, and no active exploitation has been reported. The vulnerability was published on November 3, 2025, with the issue reserved on October 29, 2025. The lack of authentication requirement increases the risk, but the limited impact on confidentiality and availability moderates the overall severity. Organizations using this plugin should be aware of the risk and prepare to apply patches once available.

For European organizations, the primary impact of CVE-2025-64294 is the potential unauthorized modification of website features controlled by the WP Snow Effect plugin. This can lead to integrity issues such as unauthorized changes to site appearance or behavior, which may undermine user trust and brand reputation. While the vulnerability does not directly expose sensitive data or cause service outages, attackers could exploit it as a foothold for further attacks or to deface websites. Organizations in sectors heavily reliant on WordPress for customer engagement, such as e-commerce, media, and public services, may face reputational damage or indirect financial losses. Additionally, unauthorized changes could violate compliance requirements related to website integrity and security. Since the vulnerability requires no authentication and can be exploited remotely, the risk is elevated for publicly accessible WordPress sites using this plugin. The absence of known exploits in the wild currently limits immediate risk but does not preclude future exploitation.

1. Monitor official d3wp and WordPress plugin repositories for updates or patches addressing CVE-2025-64294 and apply them promptly once available. 2. Until patches are released, restrict access to the WP Snow Effect plugin’s administrative functions by limiting WordPress user roles and permissions strictly to trusted administrators. 3. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting the plugin’s endpoints or functions. 4. Conduct regular security audits and penetration tests focusing on plugin vulnerabilities and access controls. 5. Consider disabling or uninstalling the WP Snow Effect plugin if it is not essential to reduce attack surface. 6. Employ server-level access controls and monitoring to detect anomalous activities related to plugin usage. 7. Educate site administrators about the risks of unauthorized plugin access and enforce strong authentication and session management practices.
