CVE-2025-11427 is a Blind Server-Side Request Forgery (SSRF) vulnerability identified in the WP Migrate Lite – WordPress Migration Made Easy plugin, affecting all versions up to and including 2.7.6. The flaw resides in the handling of the wpmdb_flush AJAX action, which can be invoked without authentication. An attacker can exploit this by sending crafted HTTP requests that cause the server to initiate outbound HTTP requests to arbitrary destinations. Because the vulnerability is 'blind,' the attacker does not receive direct responses from the targeted internal services but can infer information based on timing or side effects. SSRF vulnerabilities like this can be leveraged to scan internal networks, access metadata services, or interact with otherwise inaccessible internal resources, potentially leading to further compromise. The CVSS v3.1 score of 5.8 reflects a medium severity, considering the vulnerability's network attack vector, lack of required privileges or user interaction, and limited impact confined to confidentiality. No patches or known exploits are currently reported, but the vulnerability's presence in a widely used WordPress plugin increases the risk profile. The vulnerability is categorized under CWE-918, which covers SSRF issues where the server is tricked into making unintended requests. The vulnerability's exploitation scope is significant because WordPress is widely deployed, and the plugin is popular for migration tasks, often installed on production sites with sensitive data.

For European organizations, the impact of this SSRF vulnerability can be significant, especially for those relying on WordPress sites with the WP Migrate Lite plugin installed. Exploitation could allow attackers to perform internal network reconnaissance, potentially exposing sensitive internal services, APIs, or cloud metadata endpoints that are not externally accessible. This could lead to further attacks such as privilege escalation, lateral movement, or data exfiltration. Although the vulnerability does not directly compromise data integrity or availability, the confidentiality impact could expose sensitive configuration or infrastructure details. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, could face compliance risks if internal information is leaked. The unauthenticated nature of the vulnerability increases the risk of automated scanning and exploitation attempts, potentially leading to widespread reconnaissance activities targeting European infrastructure. The lack of known exploits in the wild currently reduces immediate risk, but the medium severity and broad attack surface warrant proactive mitigation.

European organizations should immediately audit their WordPress installations to identify the presence of the WP Migrate Lite plugin and verify the version in use. Since no official patches are currently available, organizations should consider the following mitigations: 1) Temporarily disable or remove the WP Migrate Lite plugin until a patch is released. 2) Implement web application firewall (WAF) rules to detect and block suspicious requests targeting the wpmdb_flush AJAX action, especially those originating from unauthenticated sources. 3) Restrict outbound HTTP requests from web servers hosting WordPress sites to only trusted destinations, limiting the ability of SSRF to reach internal services. 4) Monitor web server logs for unusual or repeated requests to the vulnerable AJAX endpoint to detect potential exploitation attempts. 5) Harden internal network segmentation and access controls to minimize the impact of any SSRF-based reconnaissance. 6) Stay updated with vendor advisories and apply patches promptly once available. These steps go beyond generic advice by focusing on immediate plugin management, network egress filtering, and targeted detection.
