CVE-2026-53594 — FreeScout has Arbitrary File Read in App Logs Viewer via Forged Encrypted Path

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.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (medium)+3
CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
