CVE-2025-2940 is a Server-Side Request Forgery (SSRF) vulnerability identified in the Ninja Tables – Easy Data Table Builder WordPress plugin developed by techjewel. This vulnerability affects all versions up to and including 5.0.18. The flaw exists in the handling of the args[url] parameter, which allows unauthenticated attackers to craft requests that the vulnerable web application then makes to arbitrary internal or external locations. SSRF vulnerabilities enable attackers to bypass network access controls by leveraging the server as a proxy, potentially accessing internal services that are otherwise inaccessible from the internet. In this case, the attacker can use the vulnerability to query and modify information from internal services, which may include sensitive internal APIs, metadata services, or other protected resources. The CVSS v3.1 base score is 7.2 (high severity), reflecting that the vulnerability can be exploited remotely without authentication or user interaction, has low attack complexity, and impacts confidentiality and integrity, though it does not affect availability. The vulnerability has been publicly disclosed and assigned a CVE identifier, but as of the published date, no known exploits in the wild have been reported. The lack of available patches at the time of disclosure increases the urgency for mitigation. The vulnerability’s scope is significant because WordPress is widely used across many organizations, and Ninja Tables is a popular plugin for managing data tables, making many websites potentially vulnerable if they have this plugin installed and not updated.

For European organizations, this SSRF vulnerability poses a substantial risk, especially for those relying on WordPress sites with the Ninja Tables plugin installed. Exploitation could lead to unauthorized internal network reconnaissance, data leakage, and unauthorized modification of internal service data. This can compromise the confidentiality and integrity of sensitive information, including internal APIs, databases, or configuration endpoints. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the sensitive nature of their internal services and regulatory requirements around data protection (e.g., GDPR). The ability to perform SSRF without authentication and user interaction increases the attack surface and risk of automated exploitation attempts. Furthermore, internal services that are not hardened or segmented properly could be fully exposed through this vulnerability, leading to potential lateral movement or further compromise within the network. The absence of known exploits in the wild currently provides a limited window for proactive mitigation before active exploitation begins.

1. Immediate action should be to update the Ninja Tables plugin to a version that addresses this vulnerability once available. Monitor vendor announcements for patches. 2. Until a patch is available, implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the args[url] parameter, especially those attempting to access internal IP ranges (e.g., 10.x.x.x, 172.16.x.x-172.31.x.x, 192.168.x.x) or localhost. 3. Restrict outbound HTTP requests from the web server hosting WordPress to only necessary external endpoints, using network-level egress filtering to prevent SSRF exploitation. 4. Harden internal services by enforcing authentication, authorization, and input validation to reduce the impact if accessed via SSRF. 5. Conduct internal network segmentation to isolate critical internal services from web-facing servers. 6. Monitor logs for unusual outbound requests originating from the WordPress server, particularly those to internal IP addresses or unexpected domains. 7. Educate web administrators about the risk and encourage regular plugin updates and security audits. 8. Consider disabling or removing the Ninja Tables plugin if it is not essential to reduce the attack surface.
