- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial

CVE-2026-62855 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 4.4 (medium) and affects freescout; fixed in 1.8.225.

## Summary

FreeScout, a self-hosted help desk and shared mailbox application, has a path traversal flaw in its App Logs viewer that lets a logged-in administrator who also knows the APP_KEY read arbitrary local files, including environment files, source code, credentials, and operating-system files, by reaching the viewer remotely over the network. Exploiting it requires the administrator role plus the APP_KEY, so the attack is not practical for ordinary users.

## Affected

- freescout-help-desk freescout: fixed in 1.8.225

## Description

FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.225, the administrator-only App Logs viewer accepts Laravel-encrypted folder and file parameters whose constructed path is checked only as a raw string. An administrator who also knows the APP_KEY can supply traversal segments that the filesystem normalizes outside storage/logs. The /app-logs/app route can then read local files accessible to the PHP worker, including environment files, source files, credentials, tokens, and operating-system files. This issue is fixed in version 1.8.225.
