CVE-2025-8021 describes a Directory Traversal vulnerability present in files-bucket-server versions up to 1.2.6. This flaw allows attackers to navigate outside the intended directory structure and potentially access arbitrary files on the server. Successful exploitation could lead to unauthorized data disclosure or modification. A fix is available in all subsequent versions, indicated by the asterisk (*).
The Directory Traversal vulnerability in files-bucket-server allows an attacker to bypass intended access controls and read arbitrary files on the server's file system. This could include configuration files containing database credentials, source code with embedded secrets, or any other sensitive data stored on the system. Successful exploitation could lead to complete compromise of the server and its data. The potential blast radius is significant, particularly if the server hosts critical application data or is part of a larger infrastructure.
CVE-2025-8021 was publicly disclosed on 2025-07-23. Currently, there are no known public proof-of-concept exploits. The EPSS score is pending evaluation. Monitor security advisories and threat intelligence feeds for any indications of active exploitation.
Applications and services relying on files-bucket-server for file storage or retrieval are at risk. This includes systems with older, unpatched installations of files-bucket-server, particularly those deployed in environments with permissive file system permissions or shared hosting configurations.
• nodejs / server:
find /path/to/files-bucket-server -type f -name "*..*"• generic web:
curl -I 'http://your-server/../../../../etc/passwd' # Check for sensitive file accessdisclosure

The primary mitigation for CVE-2025-8021 is to upgrade to a patched version of files-bucket-server. Since a specific fixed version is marked as '*', it indicates that all subsequent versions contain the fix. If an immediate upgrade is not feasible, consider implementing temporary workarounds such as restricting file system access permissions for the files-bucket-server process and carefully reviewing any user-supplied input that is used in file path construction. Implement strict input validation to prevent path manipulation. After upgrading, confirm the fix by attempting a directory traversal attack using a known payload and verifying that access is denied.
Actualice el paquete files-bucket-server a la última versión disponible. Esto solucionará la vulnerabilidad de path traversal. Ejecute `npm update files-bucket-server` o `yarn upgrade files-bucket-server` para actualizar el paquete.
