Detailsinfo

A vulnerability has been found in freescout up to 1.8.223 and classified as problematic. This vulnerability affects an unknown function of the component Path Resolution. The manipulation of the argument dl with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality. CVE summarizes:

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. FreeScout's `Manage -> Logs -> App Logs` feature uses the bundled `rap2hpoutre/laravel-log-viewer` override to decrypt a user-supplied file identifier and then pass the resolved path to Laravel's download response. Prior to version 1.8.224, the path resolution logic accepts any existing absolute path before applying the intended `storage/logs` restriction. As a result, an attacker who can access the App Logs route and forge a valid Laravel-encrypted `dl` parameter can download arbitrary server-local files readable by the PHP process, not just log files. Version 1.8.224 contains a fix.

The advisory is available at github.com. This vulnerability was named CVE-2026-53594 since 06/09/2026. The exploitation appears to be easy. The attack can be initiated remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

Upgrading to version 1.8.224 eliminates this vulnerability.
