CVE-2025-64357 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Advanced Database Cleaner plugin developed by Younes JFR, affecting all versions up to and including 3.1.6. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged HTTP request, causing the victim's browser to perform unwanted actions on a web application in which they are authenticated. In this case, the vulnerability allows attackers to execute unauthorized requests that could manipulate database cleaning operations or settings without the user's consent. The CVSS vector indicates the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), requiring the attacker to have low privileges (PR:L) but no user interaction (UI:N). The scope remains unchanged (S:U), and the impact is limited to confidentiality (C:L) with no impact on integrity or availability. This suggests that sensitive information could be exposed or leaked, but the core functionality and data integrity are not directly compromised. The vulnerability is particularly relevant for WordPress sites using this plugin, which is commonly employed to optimize and clean database entries. No known exploits have been reported in the wild, and no official patches or mitigation links are currently provided, indicating the need for vigilance and proactive defense. The vulnerability was published on October 31, 2025, and assigned a medium severity rating based on its potential impact and ease of exploitation.

For European organizations, the impact of CVE-2025-64357 primarily concerns the confidentiality of data managed through the Advanced Database Cleaner plugin. Unauthorized CSRF attacks could lead to exposure of sensitive database information or unauthorized changes to database cleaning configurations, potentially resulting in data leakage or operational misconfigurations. While the vulnerability does not directly affect data integrity or availability, the exposure of confidential information could have regulatory and reputational consequences, especially under GDPR requirements. Organizations relying on WordPress environments with this plugin installed are at risk, particularly small and medium enterprises (SMEs) that may lack robust security controls. The absence of known exploits reduces immediate risk, but the ease of exploitation and network accessibility mean attackers could develop exploits quickly. European entities handling sensitive or regulated data should consider this vulnerability a moderate threat that requires timely remediation to avoid compliance violations and data breaches.

1. Monitor official channels and vendor announcements for patches or updates addressing CVE-2025-64357 and apply them promptly once available. 2. Implement CSRF protection mechanisms such as synchronizer tokens or double-submit cookies within the plugin or at the application level to prevent unauthorized request forgery. 3. Restrict access to the Advanced Database Cleaner plugin’s administrative interfaces to trusted users only, employing role-based access controls and the principle of least privilege. 4. Use web application firewalls (WAFs) to detect and block suspicious CSRF attack patterns targeting the plugin’s endpoints. 5. Educate users and administrators about the risks of CSRF and encourage cautious behavior regarding unsolicited links or emails. 6. Regularly audit WordPress plugins and remove or replace those that are outdated or no longer maintained to reduce attack surface. 7. Employ security plugins that provide additional CSRF protections and monitoring capabilities for WordPress environments. 8. Conduct periodic security assessments and penetration testing focusing on plugin vulnerabilities and web application security.
