CVE-2025-10048 is an SQL Injection vulnerability identified in the My auctions allegro plugin for WordPress, affecting all versions up to and including 3.6.31. The root cause is insufficient escaping and lack of prepared statements for the 'order' parameter, which is user-supplied. This flaw allows authenticated users with administrator-level privileges or higher to append arbitrary SQL queries to existing database commands. The injection occurs because the plugin fails to properly neutralize special SQL elements, violating CWE-89 standards. Although exploitation requires high privileges, an attacker could leverage this to extract sensitive information from the backend database, such as user data, configuration details, or other confidential records. The vulnerability does not directly affect data integrity or availability but compromises confidentiality. The CVSS 3.1 score is 4.9 (medium), reflecting the network attack vector, low attack complexity, and requirement for high privileges but no user interaction. No public exploits have been reported yet, but the vulnerability has been officially published and reserved since September 2025. The absence of patches or updates at the time of reporting indicates a need for immediate attention from site administrators.

For European organizations, the primary impact is the potential unauthorized disclosure of sensitive data stored within WordPress databases using the vulnerable plugin. This could include personal data protected under GDPR, leading to regulatory penalties and reputational damage. Since the vulnerability requires administrator-level access, the risk is heightened if internal accounts are compromised or if malicious insiders exist. Exploitation could facilitate further attacks by revealing credentials or configuration details. E-commerce sites or auction platforms using this plugin may face data breaches affecting customers and business operations. Although the vulnerability does not directly disrupt service availability or data integrity, the confidentiality breach alone can have significant legal and financial consequences under European data protection laws. Organizations relying on WordPress plugins for critical business functions should consider this vulnerability a serious risk to their data security posture.

1. Immediately restrict administrator-level access to trusted personnel only and enforce strong authentication mechanisms such as multi-factor authentication (MFA). 2. Apply strict input validation and sanitization on the 'order' parameter and any other user-supplied inputs within the plugin code. 3. Implement prepared statements or parameterized queries to prevent SQL injection vulnerabilities. 4. Monitor database query logs for unusual or unexpected SQL commands that could indicate exploitation attempts. 5. Regularly audit WordPress plugins and remove or replace those that are unsupported or have known vulnerabilities. 6. If a patch becomes available, apply it promptly. 7. Consider deploying Web Application Firewalls (WAFs) with rules to detect and block SQL injection patterns targeting this plugin. 8. Conduct security awareness training for administrators to recognize and prevent credential compromise. 9. Backup databases regularly and ensure backups are securely stored to enable recovery if needed.
