The vulnerability in alexusmai laravel-file-manager version 3.3.1 and below is a directory traversal issue within the zip/archiving functionality. This occurs due to improper validation of user-supplied paths during archive creation. Attackers can exploit this by submitting crafted requests containing path traversal sequences like “../” to reference files outside the intended directory. The application fails to sanitize these inputs before passing them to archiving commands, such as PHP’s ZipArchive or system zip utilities. Specifically, when a user requests to archive files, the input paths are concatenated without canonicalization, allowing access to parent directories. For example, an attacker could specify a path like “../../etc/passwd” to include sensitive system files in the generated archive. The vulnerability is accessible via authenticated web requests to the file manager’s archiving endpoint. The lack of server-side path checks enables unauthorized file inclusion, potentially leading to data exfiltration. This flaw is common in web applications that handle file operations without strict boundary controls. In this Laravel package, the vulnerability arises from trusting user input for file paths without verifying they remain within the allowed base directory. The severity is rated low as it requires authentication and may not directly enable code execution. However, it can compromise confidentiality by exposing critical files. Mitigation involves updating to a fixed version or implementing robust path validation routines.
Platform: alexusmai laravel-file-manager
Version: 3.3.1 below
Vulnerability: Directory Traversal
Severity: Low
date: Dec 3 2025
Prediction: Dec 10 2025
What Undercode Say:
Analytics
curl -X POST http://localhost/laravel-file-manager/zip -d “paths[]=../../etc/passwd”
addFile($path); ?>
grep -r “addFile” vendor/alexusmai/laravel-file-manager/
How Exploit:
Send POST request with traversal sequences to zip endpoint.
Authenticate then craft archive containing sensitive files.
Use paths like “../../.env” to leak configuration data.
Protection from this CVE:
Update to patched version.
Validate and sanitize input paths.
Use realpath() for canonicalization.
Impact:
Unauthorized file access.
Data leakage exposure.
Potential system compromise.
