CVE-2025-11510 is an improper authorization vulnerability (CWE-285) found in the FileBird – WordPress Media Library Folders & File Manager plugin developed by ninjateam. The vulnerability arises from a missing capability check on the REST API endpoint /filebird/v1/fb-wipe-clear-all-data, which is responsible for wiping and clearing all plugin configuration data. This flaw affects all versions of the plugin up to and including 6.4.9. An authenticated attacker with author-level privileges or higher can invoke this endpoint to reset the plugin’s configuration without proper authorization. Since the vulnerability requires authentication but no additional user interaction, it can be exploited by any user with author or above roles, which are common in collaborative WordPress environments. The impact is primarily on the integrity of the plugin’s configuration data, potentially disrupting media folder organization and management. The vulnerability does not affect confidentiality or availability directly and does not require elevated privileges beyond author-level access. No public exploits have been reported to date. The CVSS v3.1 base score is 4.3, indicating a medium severity level. The vulnerability highlights the importance of enforcing capability checks on sensitive REST API endpoints in WordPress plugins to prevent unauthorized configuration changes.

The primary impact of this vulnerability is the unauthorized modification of the FileBird plugin’s configuration data, which can disrupt the organization and management of media files within WordPress sites. For organizations relying heavily on media management for content workflows, this could lead to operational inefficiencies, loss of productivity, and potential confusion among content creators and administrators. While the vulnerability does not directly expose sensitive data or cause denial of service, the integrity compromise could indirectly affect site management and user experience. Attackers with author-level access, which is a relatively common privilege level in multi-user WordPress environments, can exploit this flaw, increasing the risk in collaborative or multi-editor setups. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation. Organizations with large WordPress deployments using the FileBird plugin should consider this vulnerability a moderate risk that could affect site stability and content management integrity.

To mitigate CVE-2025-11510, organizations should first check for and apply any official patches or updates released by ninjateam addressing this vulnerability. If no patch is available, administrators should restrict author-level privileges to trusted users only, minimizing the risk of exploitation. Additionally, implementing Web Application Firewall (WAF) rules to monitor and block unauthorized REST API calls to /filebird/v1/fb-wipe-clear-all-data can help prevent exploitation attempts. Site administrators can also audit user roles and permissions regularly to ensure that only necessary users have author or higher access. Disabling or removing the FileBird plugin temporarily until a fix is available is another option for high-risk environments. Monitoring WordPress logs for unusual API activity related to the vulnerable endpoint can provide early detection of exploitation attempts. Finally, educating content editors and administrators about the risks associated with privilege misuse can reduce insider threat vectors.
