CVE-2025-10037 identifies a SQL Injection vulnerability in the Featured Image from URL (FIFU) WordPress plugin, affecting all versions up to and including 5.2.7. The vulnerability stems from improper neutralization of special elements in SQL commands (CWE-89) within the get_posts_with_internal_featured_image() function. Specifically, the plugin fails to adequately escape user-supplied parameters and does not sufficiently prepare the SQL query, allowing an attacker with administrator privileges to append arbitrary SQL commands. This can lead to unauthorized extraction of sensitive data from the WordPress database. The vulnerability requires authenticated access at a high privilege level (administrator or above), no user interaction, and can be exploited remotely over the network. The CVSS 3.1 vector indicates network attack vector (AV:N), low attack complexity (AC:L), high privileges required (PR:H), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). No patches or exploits are currently publicly available, but the risk remains significant due to the potential data exposure. The plugin is widely used in WordPress environments, making affected sites vulnerable until remediated.

The primary impact of this vulnerability is the unauthorized disclosure of sensitive information stored in the WordPress database. An attacker with administrator access can exploit the SQL Injection flaw to extract data such as user credentials, personal information, or site configuration details. Although the vulnerability does not affect data integrity or availability, the confidentiality breach can lead to further attacks, including privilege escalation, identity theft, or targeted phishing campaigns. Organizations relying on the Fifu plugin for featured image management face increased risk of data leakage, especially if they have multiple administrators or weak internal controls. The medium CVSS score reflects the requirement for high privileges, limiting exploitation to insiders or compromised accounts, but the ease of remote exploitation without user interaction increases the threat. This vulnerability could undermine trust in affected websites and lead to regulatory compliance issues if sensitive user data is exposed.

To mitigate CVE-2025-10037, organizations should immediately update the Featured Image from URL (FIFU) plugin to a patched version once available. In the absence of an official patch, administrators should consider disabling or uninstalling the plugin to eliminate the attack surface. Restrict administrator access strictly to trusted personnel and enforce strong authentication mechanisms such as multi-factor authentication to reduce the risk of credential compromise. Conduct regular audits of administrator accounts and monitor database queries for unusual activity indicative of SQL Injection attempts. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns targeting the vulnerable function. Additionally, implement database access controls to limit the exposure of sensitive data even if SQL Injection occurs. Developers maintaining the plugin should refactor the vulnerable function to use parameterized queries or prepared statements to ensure proper input sanitization and prevent injection. Finally, maintain regular backups and incident response plans to quickly recover from potential data breaches.
