CVE-2025-3775 is a Server-Side Request Forgery (SSRF) vulnerability identified in the ShopLentor plugin for WordPress, which is a WooCommerce builder designed for Elementor and Gutenberg page builders. The vulnerability affects all versions up to and including 3.1.2. The root cause lies in the woolentor_template_proxy function, which improperly handles user-supplied input to make server-side web requests. This flaw allows unauthenticated attackers to coerce the vulnerable web application into sending arbitrary HTTP requests to internal or external systems. SSRF vulnerabilities are particularly dangerous because they can be used to bypass network access controls, enabling attackers to interact with internal services that are not directly exposed to the internet. In this case, the attacker can query internal endpoints, potentially extracting sensitive information or modifying data if internal services accept such requests. The vulnerability does not require authentication or user interaction, increasing its risk profile. Although no known exploits are currently reported in the wild, the presence of this SSRF in a widely used e-commerce plugin for WordPress sites makes it a significant concern. The plugin’s integration with WooCommerce and popular page builders like Elementor and Gutenberg means that many online shops and business websites could be affected. The lack of an official patch at the time of reporting further elevates the urgency for mitigation. Given that the vulnerability allows arbitrary web requests from the server, it could be leveraged for reconnaissance, internal network scanning, or even pivoting attacks to compromise other internal assets or cloud metadata services if hosted in cloud environments. This vulnerability is classified under CWE-918, which covers SSRF issues where the server is tricked into making unintended requests.

For European organizations, the impact of this SSRF vulnerability can be substantial, especially for those relying on WordPress-based e-commerce platforms using the ShopLentor plugin. Confidentiality risks arise from the potential to access internal services that may contain sensitive business data, customer information, or configuration details. Integrity could be compromised if internal services allow modification through the SSRF vector, potentially leading to data tampering or unauthorized changes in business logic. Availability impacts are possible if the attacker uses SSRF to trigger resource exhaustion or denial-of-service conditions on internal services. Given the widespread adoption of WooCommerce and Elementor in Europe’s small to medium-sized enterprises (SMEs), many online retailers could be exposed, risking customer trust and regulatory compliance under GDPR if personal data is leaked or manipulated. Additionally, SSRF can be a stepping stone for more complex attacks, such as lateral movement within corporate networks or cloud environments, which could lead to broader compromises. The vulnerability’s unauthenticated nature means attackers can exploit it without any credentials, increasing the likelihood of automated scanning and exploitation attempts. The absence of known exploits currently suggests a window of opportunity for proactive defense, but also a risk that attackers may develop exploits rapidly once the vulnerability becomes widely known.

Immediate mitigation should focus on restricting the vulnerable plugin’s ability to make arbitrary outbound HTTP requests. Network-level controls such as egress filtering should be implemented to limit the web server’s outbound connections to only trusted destinations. Web application firewalls (WAFs) can be configured with custom rules to detect and block suspicious requests targeting the woolentor_template_proxy function or unusual request patterns indicative of SSRF attempts. Administrators should monitor logs for anomalous outbound requests and unusual internal service access patterns. Until an official patch is released, consider disabling or removing the ShopLentor plugin if it is not essential. If the plugin is critical, isolate the WordPress environment in a segmented network zone with minimal access to internal services. Employ strict input validation and sanitization on any user-controllable parameters related to the plugin, if customization is possible. Regularly update all WordPress components and monitor vendor communications for patch releases. Additionally, organizations should conduct internal scans to identify any exposed internal services that could be targeted via SSRF and harden those services by enforcing authentication and access controls. Finally, implement comprehensive incident detection and response capabilities to quickly identify and mitigate any exploitation attempts.
