CVE-2025-11457 is a critical security vulnerability identified in the EasyCommerce – AI-Powered, Fast & Beautiful WordPress Ecommerce Plugin, affecting all versions from 0.9.0-beta2 to 1.5.0. The root cause is improper privilege management (CWE-269) in the plugin's REST API, specifically the /easycommerce/v1/orders endpoint. This endpoint does not properly validate or restrict the roles that can be assigned during user registration, allowing attackers to specify elevated roles such as administrator. Because the vulnerability can be exploited without authentication (AV:N) and requires no user interaction (UI:N), an unauthenticated attacker can escalate privileges to administrator level remotely. The vulnerability impacts confidentiality, integrity, and availability severely, as attackers gain full control over the WordPress site, potentially leading to data theft, site defacement, or further malware deployment. The CVSS v3.1 score of 9.8 reflects the critical nature of this flaw. Although no public exploits have been reported yet, the simplicity of exploitation and the widespread use of WordPress and its plugins make this a high-risk issue. The vulnerability was published on November 11, 2025, and no official patches have been linked yet, emphasizing the need for immediate attention from site administrators.

For European organizations, this vulnerability poses a severe risk to ecommerce platforms running WordPress with the EasyCommerce plugin. Successful exploitation results in full administrative access, enabling attackers to manipulate or steal sensitive customer data, disrupt ecommerce operations, and deploy further malicious payloads. This can lead to financial losses, reputational damage, and regulatory penalties under GDPR due to data breaches. The ecommerce nature of the plugin means that payment information and personally identifiable information (PII) are at risk. Additionally, compromised sites can be used as launchpads for broader attacks within corporate networks. The critical severity and unauthenticated exploitability increase the likelihood of rapid exploitation, especially targeting high-value European ecommerce businesses. The impact extends beyond individual sites to affect customer trust and compliance with European data protection laws.

Immediate mitigation steps include disabling the EasyCommerce plugin until a vendor patch is released. Administrators should monitor and restrict access to the /easycommerce/v1/orders REST API endpoint using web application firewalls (WAFs) or custom access control rules to block unauthenticated requests. Implementing strict role assignment validation at the application or server level can prevent unauthorized role escalation. Regularly audit user roles and registrations for suspicious privilege assignments. Organizations should subscribe to vendor and security advisories for timely patch releases and apply updates promptly once available. Employing intrusion detection systems (IDS) to monitor anomalous API usage and enforcing least privilege principles on WordPress installations will reduce attack surfaces. Backup critical data and have incident response plans ready to address potential compromises. Finally, consider isolating ecommerce platforms from other critical infrastructure to limit lateral movement in case of exploitation.
