CVE-2025-47664 is a Server-Side Request Forgery (SSRF) vulnerability identified in the ThimPress WP Pipes WordPress plugin, affecting versions up to and including 1.4.2. SSRF vulnerabilities occur when an attacker can manipulate a server to send HTTP requests to arbitrary domains or internal systems, potentially bypassing network restrictions and accessing sensitive resources. In this case, the vulnerability allows an authenticated user with high privileges to induce the server hosting WP Pipes to make unintended requests. The CVSS 3.1 base score is 4.4 (medium severity), reflecting that exploitation requires high privileges and no user interaction, with a high attack complexity. The impact includes limited confidentiality and integrity loss, but no availability impact. The vulnerability’s scope is classified as changed, indicating that exploitation could affect resources beyond the initially vulnerable component. No known exploits are currently observed in the wild, and no patches have been published yet. The vulnerability is categorized under CWE-918, which covers SSRF issues. Given that WP Pipes is a WordPress plugin used for data integration and automation workflows, this SSRF could be leveraged to access internal services, perform reconnaissance, or potentially pivot attacks within the hosting environment. However, the requirement for high privileges limits the attack surface to users who already have significant access, such as administrators or trusted editors.

For European organizations, the impact of this SSRF vulnerability depends largely on the deployment of the WP Pipes plugin within their WordPress environments. Organizations using WP Pipes for content automation or integration could face risks of internal network reconnaissance or unauthorized access to internal services if an attacker gains high-level user credentials. This could lead to exposure of sensitive internal APIs, databases, or cloud metadata services, potentially facilitating further attacks or data leakage. While the vulnerability does not directly allow denial of service or full system compromise, the confidentiality and integrity of internal resources could be compromised. European entities in sectors with stringent data protection requirements (e.g., finance, healthcare, government) could face compliance risks if internal data is exposed. The medium severity and high privilege requirement reduce the likelihood of widespread exploitation but do not eliminate risk, especially in environments with weak access controls or credential management.

To mitigate this vulnerability, European organizations should first verify if WP Pipes is installed and identify the version in use. Immediate steps include restricting administrative access to trusted personnel only and enforcing strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of credential compromise. Network segmentation should be employed to limit the WordPress server’s ability to access sensitive internal resources or metadata endpoints. Web application firewalls (WAFs) can be configured to detect and block suspicious outbound requests originating from the WordPress server. Organizations should monitor logs for unusual internal requests or traffic patterns indicative of SSRF exploitation attempts. Since no official patch is currently available, organizations should follow ThimPress and security advisories closely for updates. Applying the principle of least privilege to WordPress user roles and regularly auditing plugin usage and permissions will further reduce risk. Additionally, consider deploying runtime application self-protection (RASP) solutions that can detect and prevent SSRF attacks in real time.
