CVE-2025-64368 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Bard plugin developed by Mikado-Themes for WordPress. The vulnerability affects all versions up to and including 1.6. 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 Bard plugin lacks sufficient CSRF protections, such as anti-CSRF tokens or proper request validation, allowing attackers to craft malicious web pages that, when visited by authenticated users, can trigger unauthorized actions within the plugin. These actions could include modifying content, changing settings, or other administrative tasks depending on the plugin's capabilities. The vulnerability requires the victim to be logged into the WordPress site with sufficient privileges and to visit a malicious site or click a crafted link. No public exploits or patches are currently available, but the vulnerability has been officially published and assigned a CVE identifier. The Bard plugin is used primarily for content management and creation, making the integrity of content and site configuration the primary concern. The lack of a CVSS score necessitates an assessment based on impact and exploitability factors.

For European organizations, this vulnerability could lead to unauthorized modifications of website content or configurations, potentially damaging brand reputation, causing misinformation, or disrupting service availability. Since WordPress powers a significant portion of websites in Europe, and Mikado-Themes Bard is a popular plugin for content management, the risk is non-negligible. Attackers exploiting this vulnerability could alter published content, inject malicious code, or change site settings, which might facilitate further attacks such as phishing or malware distribution. The requirement for user authentication and interaction limits the scope but does not eliminate risk, especially for organizations with many users or administrators. The impact on confidentiality is limited, but integrity and availability could be significantly affected. This could also have compliance implications under GDPR if unauthorized changes lead to data exposure or service interruptions.

Organizations should monitor Mikado-Themes announcements and apply security patches promptly once released. Until patches are available, administrators should minimize the number of users with high privileges and educate users about the risks of visiting untrusted websites while logged into administrative accounts. Implementing Web Application Firewalls (WAFs) with rules to detect and block CSRF attack patterns can provide interim protection. Additionally, site administrators can enforce multi-factor authentication (MFA) to reduce the risk of session hijacking and unauthorized actions. Reviewing and restricting plugin permissions and disabling unused features can also reduce the attack surface. Regular security audits and monitoring for unusual activity on WordPress sites using Bard are recommended.
