CVE-2025-52713 is a Server-Side Request Forgery (SSRF) vulnerability identified in the BoldGrid Post and Page Builder plugin, a visual drag-and-drop editor used for WordPress websites. This vulnerability affects versions up to and including 1.27.8. SSRF vulnerabilities occur when an attacker can manipulate a server to make unintended HTTP requests, potentially allowing access to internal resources or sensitive information that is otherwise inaccessible externally. In this case, the vulnerability allows an authenticated user with at least low privileges (PR:L) to induce the server to send crafted requests to arbitrary URLs without requiring any user interaction (UI:N). The CVSS 3.1 base score is 6.4, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N) shows that the attack can be launched remotely over the network with low attack complexity, requires privileges, and results in partial confidentiality and integrity impacts, but no availability impact. The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. Although no public exploits are currently known, the vulnerability could be leveraged to access internal services, metadata endpoints, or sensitive backend systems, potentially leading to information disclosure or further compromise. The lack of a patch link suggests that a fix may not yet be publicly available or is pending release. Given the plugin’s integration with WordPress, a widely used CMS, the vulnerability could be present on many websites using this plugin version, especially those that allow authenticated users to create or edit content with the builder.

For European organizations, this SSRF vulnerability poses a risk primarily to websites and web applications utilizing the BoldGrid Post and Page Builder plugin. Exploitation could lead to unauthorized internal network scanning, access to sensitive internal services (such as databases, internal APIs, or cloud metadata services), and potential leakage of confidential information. This can undermine the confidentiality and integrity of organizational data. While the vulnerability does not directly impact availability, the information gained could facilitate further attacks, including privilege escalation or lateral movement within the network. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, could face compliance risks and reputational damage if sensitive data is exposed. Additionally, websites compromised through this vulnerability could be used as pivot points for broader attacks or to host malicious content, affecting trust and user safety. The requirement for authenticated access limits the attack surface but does not eliminate risk, especially in environments with multiple users or weak access controls.

1. Immediate mitigation should include restricting access to the BoldGrid Post and Page Builder plugin to trusted users only, enforcing strong authentication and role-based access controls to minimize the number of users who can exploit this vulnerability. 2. Monitor and audit user activities related to content creation and editing to detect suspicious behavior indicative of SSRF exploitation attempts. 3. Implement network-level controls such as egress filtering and internal firewall rules to prevent the web server from making unauthorized outbound requests to internal services or sensitive endpoints. 4. Use Web Application Firewalls (WAFs) with custom rules to detect and block SSRF attack patterns targeting the plugin’s endpoints. 5. Regularly update and patch the BoldGrid plugin as soon as a security fix is released by the vendor. 6. Conduct internal vulnerability assessments and penetration testing focusing on SSRF vectors within the web application environment. 7. Educate administrators and users about the risks of SSRF and the importance of limiting plugin access and privileges.
