CVE-2025-64271 is a Cross-Site Request Forgery (CSRF) vulnerability found in the HasThemes WP Plugin Manager WordPress plugin, affecting all versions up to 1.4.7. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application, causing the application to perform unintended actions on behalf of the user. In this case, the vulnerability allows an attacker to perform unauthorized actions within the WP Plugin Manager interface without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact primarily affects confidentiality and integrity, potentially allowing attackers to alter plugin configurations or settings, which could lead to further exploitation or compromise of the WordPress environment. The vulnerability does not affect availability. The plugin is used to manage other WordPress plugins, so unauthorized changes could disrupt site functionality or security posture. Although no known exploits are reported in the wild, the medium CVSS score of 6.5 reflects the ease of exploitation and potential impact. The vulnerability was published on November 13, 2025, and no official patches or fixes have been linked yet. The issue was assigned by Patchstack and reserved on October 29, 2025. Given the nature of WordPress as a widely used CMS, this vulnerability could have broad implications if left unaddressed.

For European organizations, this vulnerability could lead to unauthorized modification of WordPress plugin settings, potentially compromising website integrity and confidentiality. Organizations relying on WordPress for e-commerce, media, or public-facing services may face risks of unauthorized content changes, data leakage, or further exploitation through compromised plugins. While availability is not directly impacted, the integrity breach could facilitate subsequent attacks such as malware injection or privilege escalation. The ease of exploitation without authentication or user interaction increases the threat level, especially for sites with multiple administrators or less stringent access controls. This could undermine trust in affected websites and lead to reputational damage or regulatory scrutiny under GDPR if personal data is involved. The absence of known exploits currently provides a window for proactive mitigation, but the widespread use of WordPress in Europe makes timely response critical.

1. Monitor HasThemes and WordPress plugin repositories for official patches or updates addressing CVE-2025-64271 and apply them promptly. 2. Implement strict access controls to the WordPress admin panel, limiting plugin management capabilities to trusted administrators only. 3. Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious CSRF attack patterns targeting plugin management endpoints. 4. Enforce the use of anti-CSRF tokens in all forms and requests related to plugin management to prevent unauthorized request forgery. 5. Regularly audit WordPress user roles and permissions to minimize the number of users with plugin management privileges. 6. Educate administrators about the risks of CSRF and encourage cautious behavior when browsing untrusted sites while logged into WordPress admin. 7. Consider isolating critical WordPress instances or using security plugins that add additional layers of request validation. 8. Maintain regular backups of WordPress sites to enable quick restoration in case of compromise.
