CVE-2025-6986 in FileBird Plugin
Summary
by MITRE • 08/06/2025
The FileBird – WordPress Media Library Folders & File Manager plugin for WordPress is vulnerable to SQL Injection via the 'search' parameter in all versions up to, and including, 6.4.8 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Author-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The FileBird WordPress plugin presents a critical sql injection vulnerability that undermines the security posture of wordpress installations. This vulnerability affects all versions up to and including 6.4.8 and stems from inadequate input sanitization practices within the plugin's handling of user-supplied data. The flaw specifically manifests through the 'search' parameter which fails to properly escape or prepare user input before incorporating it into existing sql queries. Security researchers have identified that this weakness allows authenticated attackers with author-level privileges or higher to manipulate the underlying database queries through crafted input sequences.
The technical implementation of this vulnerability demonstrates a classic sql injection vector where the plugin's database interaction lacks proper parameterization or escaping mechanisms. When an authenticated user with author privileges submits a search query, the plugin processes the input without adequate sanitization, allowing malicious sql fragments to be appended to existing queries. This vulnerability operates at the application layer and leverages the principle that user input should never be directly incorporated into sql statements without proper validation and escaping. The flaw aligns with common weakness enumerations such as cwe-89 which specifically addresses sql injection vulnerabilities in software applications.
The operational impact of this vulnerability extends beyond simple data extraction capabilities to potentially enable complete database compromise. Attackers with author-level access can leverage this vulnerability to retrieve sensitive information including user credentials, administrative details, and other confidential data stored within the wordpress database. The attack surface is particularly concerning because it requires only author-level privileges, which are often more easily obtained than administrator-level access in many wordpress installations. This vulnerability can facilitate further attacks including privilege escalation, data manipulation, and potential lateral movement within the compromised environment.
Organizations utilizing the FileBird plugin must implement immediate mitigations to protect their wordpress installations from exploitation. The primary recommendation involves upgrading to the latest available version of the plugin where the sql injection vulnerability has been addressed through proper input sanitization and parameterized query implementation. System administrators should also consider implementing additional security measures such as web application firewalls, input validation rules, and monitoring for suspicious search query patterns. Security teams should conduct thorough vulnerability assessments to identify all instances of the affected plugin version across their wordpress environments and establish automated patch management processes to prevent future occurrences of similar vulnerabilities. The mitigation strategy should align with established security frameworks and include regular security audits to ensure compliance with industry standards and best practices for protecting web applications from sql injection attacks.
