CVE-2025-54048 is a critical SQL Injection vulnerability identified in the miniOrange Custom API for WordPress (WP) plugin, affecting all versions up to and including 4.2.2. The vulnerability stems from improper neutralization of special elements used in SQL commands (CWE-89), allowing an unauthenticated attacker to inject malicious SQL code via crafted requests to the API. The CVSS 3.1 base score of 9.3 reflects the high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The impact on confidentiality is high (C:H), while integrity is not impacted (I:N), and availability impact is low (A:L). This means that an attacker can extract sensitive data from the backend database without altering data or causing significant service disruption. The vulnerability is particularly dangerous because it requires no authentication or user interaction, enabling remote attackers to exploit it at scale. Although no known exploits are currently reported in the wild, the critical severity and ease of exploitation make it a high-priority issue for organizations using this plugin. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability affects the Custom API for WP plugin, which is used to extend WordPress functionality via custom API endpoints, often handling sensitive data and authentication tokens, thus increasing the risk profile of this flaw.

For European organizations, this vulnerability poses a significant risk, especially for those relying on WordPress sites with the miniOrange Custom API plugin installed. Exploitation could lead to unauthorized disclosure of sensitive customer data, internal business information, or credentials stored in the backend database. This can result in data breaches violating GDPR and other data protection regulations, leading to legal penalties and reputational damage. The critical nature of the vulnerability and its ability to be exploited remotely without authentication means attackers can target a wide range of organizations indiscriminately, including e-commerce, government portals, healthcare, and financial services that use WordPress. The potential for data exfiltration could also facilitate further attacks such as identity theft, fraud, or lateral movement within compromised networks. Additionally, the changed scope impact suggests that exploitation might affect other connected systems or services, amplifying the damage. Given the widespread use of WordPress in Europe and the popularity of miniOrange plugins for enhanced API capabilities, the threat is material and demands immediate attention.

1. Immediate action should be to monitor official miniOrange channels and Patchstack advisories for the release of a security patch addressing CVE-2025-54048. 2. Until a patch is available, disable or remove the Custom API for WP plugin if it is not essential to business operations to eliminate the attack surface. 3. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the plugin's API endpoints. Custom signatures can be developed based on known SQL injection patterns and the plugin's API request structure. 4. Conduct thorough code reviews and penetration testing on the API endpoints to identify any other injection points or related vulnerabilities. 5. Restrict access to the API endpoints by IP whitelisting or VPN access where feasible, limiting exposure to trusted networks only. 6. Employ database activity monitoring to detect unusual query patterns indicative of SQL injection exploitation attempts. 7. Ensure regular backups of databases and WordPress installations are performed and securely stored to enable rapid recovery if exploitation occurs. 8. Educate development and security teams about the risks of SQL injection and the importance of input validation and parameterized queries in custom API development.
