CVE-2025-10036 identifies a SQL Injection vulnerability in the Featured Image from URL (FIFU) plugin for WordPress, specifically in the get_all_urls() function. This vulnerability arises from improper neutralization of special elements in SQL commands (CWE-89), where user-supplied input is insufficiently escaped and the SQL query is not properly prepared. The flaw allows an attacker with administrator-level privileges to append arbitrary SQL queries to existing ones, enabling extraction of sensitive information from the database. The vulnerability affects all versions up to and including 5.2.7. The CVSS 3.1 score is 4.9 (medium severity), reflecting that the attack vector is network-based, requires high privileges, no user interaction, and impacts confidentiality but not integrity or availability. Although no public exploits are known, the risk remains significant for sites with exposed admin accounts. The lack of patches at the time of publication necessitates immediate mitigation through access control and monitoring. This vulnerability highlights the importance of secure coding practices, such as parameterized queries and proper input sanitization, especially in plugins that handle user input and database queries.

For European organizations, this vulnerability poses a risk primarily to the confidentiality of sensitive data stored in WordPress databases, including user information, configuration details, and potentially business-critical content. Since exploitation requires administrator-level access, the threat is elevated in environments where admin credentials are weak, reused, or compromised. The impact is heightened for organizations relying on the FIFU plugin for content management, especially those in sectors with strict data protection regulations like GDPR. Unauthorized data disclosure could lead to regulatory penalties, reputational damage, and potential follow-on attacks leveraging exposed information. However, the vulnerability does not affect data integrity or availability, limiting the scope of disruption. Organizations with extensive WordPress deployments and high-value data are at increased risk, necessitating proactive defense measures.

1. Immediately audit and restrict administrator-level access to trusted personnel only, enforcing strong, unique passwords and multi-factor authentication (MFA). 2. Monitor WordPress logs and database query logs for unusual or unexpected SQL queries that may indicate exploitation attempts. 3. Disable or remove the Featured Image from URL (FIFU) plugin if it is not essential to reduce attack surface. 4. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the plugin's endpoints. 5. Regularly update WordPress core and plugins; apply patches for FIFU promptly once released by the vendor. 6. Conduct security code reviews and penetration testing focused on plugins handling user input and database interactions. 7. Employ database user permissions with the principle of least privilege, limiting the scope of SQL queries that can be executed by the web application. 8. Educate administrators on phishing and credential security to prevent privilege escalation via compromised accounts.
