CVE-2025-52711 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the BoldGrid Post and Page Builder plugin, a visual drag-and-drop editor commonly used within WordPress environments. This vulnerability affects versions up to and including 1.27.8. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting unwanted actions on a web application in which they are currently authenticated. In this case, the vulnerability permits an attacker to craft malicious requests that, when executed by an authenticated user, can cause unintended modifications to posts or pages managed by the BoldGrid plugin. The CVSS 3.1 base score of 4.3 (medium severity) reflects that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The impact is limited to integrity (I:L), with no direct confidentiality or availability impact. The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component and does not extend beyond it. No known exploits are currently reported in the wild, and no official patches have been released at the time of publication. The vulnerability stems from insufficient anti-CSRF protections, such as missing or ineffective CSRF tokens, allowing attackers to forge requests that the server accepts as legitimate. Given the plugin’s role in content management, successful exploitation could lead to unauthorized content changes, defacement, or insertion of malicious content, potentially undermining website integrity and user trust.

For European organizations, the impact of this vulnerability primarily concerns the integrity of web content managed via the BoldGrid Post and Page Builder plugin. Organizations relying on this plugin for website content management may face unauthorized content modifications, which could lead to misinformation, reputational damage, or the insertion of malicious links or scripts that could further compromise visitors. While the vulnerability does not directly compromise confidentiality or availability, the integrity breach can indirectly affect user trust and brand reputation. Sectors such as media, e-commerce, education, and government agencies that maintain public-facing websites using WordPress and BoldGrid are particularly at risk. Additionally, altered content could be leveraged in phishing campaigns or to spread disinformation, which is a significant concern in the European regulatory context, especially under GDPR and NIS Directive frameworks that emphasize data integrity and security. The absence of known exploits reduces immediate risk, but the widespread use of WordPress and its plugins in Europe means that the attack surface is considerable if attackers develop exploits.

1. Immediate mitigation involves applying any available updates or patches from BoldGrid as soon as they are released. Since no patches are currently available, organizations should monitor vendor communications closely. 2. Implement Web Application Firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the BoldGrid plugin endpoints. Custom rules can be created to validate the presence of legitimate CSRF tokens or to block anomalous POST requests without valid referrers. 3. Review and harden WordPress security configurations, including disabling or restricting plugin usage to only trusted administrators and limiting user roles to the minimum necessary privileges. 4. Employ Content Security Policy (CSP) headers to mitigate the impact of potential content injection resulting from CSRF exploitation. 5. Conduct regular security audits and penetration testing focused on web application vulnerabilities, including CSRF, to identify and remediate weaknesses proactively. 6. Educate users and administrators about the risks of CSRF and the importance of avoiding clicking on suspicious links or performing sensitive actions from untrusted sources. 7. Consider deploying multi-factor authentication (MFA) for administrative accounts to reduce the risk of session hijacking that could facilitate CSRF attacks. 8. If feasible, temporarily disable or replace the BoldGrid Post and Page Builder plugin with alternative solutions until a secure version is available.
