CVE-2025-10037 is a SQL Injection vulnerability classified under CWE-89 found in the Featured Image from URL (FIFU) WordPress plugin, versions up to and including 5.2.7. The vulnerability arises from the get_posts_with_internal_featured_image() function, which fails to properly escape user-supplied input and does not adequately prepare SQL queries before execution. This improper neutralization allows an authenticated attacker with administrator-level privileges to append malicious SQL code to existing queries. As a result, attackers can extract sensitive information from the WordPress database, such as user credentials, configuration data, or other confidential content stored therein. The vulnerability requires no user interaction but does require high privileges, limiting the attack surface to trusted users with admin access. The CVSS 3.1 base score is 4.9, reflecting a medium severity due to the need for privileged access and the impact being limited to confidentiality without affecting integrity or availability. No patches or exploits are currently publicly available, but the vulnerability is officially published and should be addressed promptly. The plugin is widely used in WordPress environments to manage featured images via URLs, making it a relevant target for attackers aiming to leverage administrator accounts to escalate data access.

For European organizations, this vulnerability poses a risk primarily to the confidentiality of sensitive data stored within WordPress databases. Organizations using the Fifu plugin on their WordPress sites could face unauthorized data disclosure if an attacker gains administrator access, which could occur through compromised credentials or insider threats. The impact is particularly significant for entities handling personal data under GDPR, as data breaches could lead to regulatory penalties and reputational damage. Although the vulnerability does not affect data integrity or availability, the exposure of sensitive information could facilitate further attacks or data misuse. Organizations with public-facing WordPress sites that rely on this plugin are at risk, especially if administrative accounts are not tightly controlled or monitored. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability details are widely known.

To mitigate this vulnerability, European organizations should first restrict administrator-level access to trusted personnel and enforce strong authentication mechanisms such as multi-factor authentication (MFA). Regularly audit administrator accounts and monitor for unusual database query patterns that could indicate exploitation attempts. Until an official patch is released, consider disabling or removing the Featured Image from URL (FIFU) plugin if feasible, or replace it with alternative plugins that do not have this vulnerability. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this plugin's functions. Additionally, ensure WordPress core and all plugins are kept up to date, and subscribe to vulnerability advisories for timely updates. Conduct regular security assessments and penetration testing focusing on WordPress environments to detect privilege escalation or injection vulnerabilities early.
