CVE-2025-64357 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Advanced Database Cleaner plugin developed by Younes JFR, affecting versions up to 3.1.6. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application in which they have privileges, causing the application to perform unwanted actions on behalf of the user. In this case, the Advanced Database Cleaner plugin does not adequately verify the origin or authenticity of requests, allowing an attacker to craft malicious web pages or links that, when visited by an authenticated administrator or user with sufficient privileges, can trigger unauthorized operations such as database cleaning or configuration changes. This vulnerability is particularly concerning because database cleaning operations can affect data integrity and availability. The vulnerability was published on October 31, 2025, but no patches or fixes have been linked yet, and no known exploits have been reported in the wild. The absence of a CVSS score requires an independent severity assessment. The vulnerability requires the victim to be authenticated, and exploitation does not require complex user interaction beyond visiting a malicious page. The plugin is typically used in WordPress environments to optimize and clean databases, making it a target in CMS-based websites. Attackers could leverage this vulnerability to disrupt website operations, cause data loss, or degrade performance by triggering unintended database cleaning tasks.

For European organizations, the impact of this CSRF vulnerability can be significant, especially for those relying on WordPress websites that utilize the Advanced Database Cleaner plugin. Successful exploitation could lead to unauthorized database cleaning operations, potentially resulting in data loss, corruption, or service disruption. This can affect the confidentiality, integrity, and availability of website data and services. Organizations in sectors such as e-commerce, government, healthcare, and finance, which often rely on CMS platforms for their web presence, could face operational disruptions and reputational damage. Additionally, the exploitation of this vulnerability could be used as a stepping stone for further attacks, such as privilege escalation or persistent compromise. Given the lack of known exploits currently, the threat is more theoretical but should be treated proactively to prevent future incidents. The impact is heightened in environments where administrative privileges are widely distributed or where security controls around plugin management are lax.

To mitigate CVE-2025-64357, organizations should: 1) Monitor for and apply security patches or updates from the plugin vendor as soon as they become available. 2) Implement anti-CSRF tokens in all forms and requests handled by the plugin to ensure requests are legitimate and originate from authorized users. 3) Restrict administrative access to the WordPress backend to trusted IP addresses or via VPN to reduce the attack surface. 4) Employ web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting the plugin. 5) Conduct regular audits of plugin usage and permissions to ensure only necessary users have administrative rights. 6) Educate users with administrative privileges about the risks of visiting untrusted websites while logged into administrative sessions. 7) Consider disabling or replacing the plugin if a timely patch is not available and the risk is deemed unacceptable. 8) Use security plugins that can detect anomalous behavior or unauthorized changes within WordPress environments.
