CVE-2025-64271 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the HasThemes WP Plugin Manager plugin for WordPress, affecting versions up to 1.4.7. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged HTTP request, which the server trusts and executes. In this case, the vulnerability allows an attacker to perform unauthorized actions on the WP Plugin Manager plugin without requiring any privileges or user interaction. The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact affects confidentiality and integrity (C:L/I:L) but does not affect availability (A:N). This means an attacker could potentially manipulate plugin settings or configurations, leading to unauthorized disclosure or modification of data managed by the plugin. The vulnerability is currently published with no known exploits in the wild, and no patch links have been provided yet. The plugin is commonly used in WordPress environments to manage other plugins, making it a critical component for site administrators. The lack of CSRF protections in the plugin's request handling allows attackers to craft malicious web pages or emails that, when visited by an authenticated admin, execute unauthorized commands. This could lead to further compromise of the WordPress site, including privilege escalation or data leakage. The vulnerability was reserved on 2025-10-29 and published on 2025-11-13, with a CVSS v3.1 base score of 6.5, indicating medium severity.

For European organizations, this vulnerability poses a risk primarily to the confidentiality and integrity of WordPress-managed websites that utilize the HasThemes WP Plugin Manager plugin. Unauthorized changes to plugin configurations could allow attackers to introduce malicious plugins, disable security controls, or exfiltrate sensitive data. This is particularly concerning for organizations relying on WordPress for public-facing websites, e-commerce platforms, or internal portals. The absence of availability impact means service disruption is unlikely, but the integrity compromise could facilitate further attacks, including data breaches or website defacement. Given the widespread use of WordPress across Europe, especially in small and medium enterprises, government agencies, and educational institutions, exploitation could lead to reputational damage, regulatory non-compliance (e.g., GDPR), and financial losses. The medium severity score reflects a moderate risk, but the ease of exploitation without authentication or user interaction increases the urgency for mitigation.

1. Monitor for official patches or updates from HasThemes and apply them immediately once available to address the CSRF vulnerability. 2. In the interim, implement web application firewall (WAF) rules to detect and block suspicious CSRF attack patterns targeting the WP Plugin Manager endpoints. 3. Restrict administrative access to the WordPress backend by IP whitelisting or VPN access to reduce exposure to remote attacks. 4. Enforce multi-factor authentication (MFA) for WordPress admin accounts to mitigate the impact of compromised credentials. 5. Review and harden WordPress security configurations, including disabling unnecessary plugins and limiting plugin management privileges to trusted users only. 6. Educate administrators about the risks of clicking on untrusted links or visiting suspicious websites while logged into WordPress admin. 7. Regularly audit plugin usage and configurations to detect unauthorized changes promptly. 8. Consider deploying security plugins that add CSRF protections or enhance request validation if patching is delayed.
