FreeScout has Zip Slip path traversal in module installation that allows arbitrary file write leading to RCE

Published Apr 21, 2026 · Updated Apr 21, 2026 · Assigned by GitHub_M

Description

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.215, FreeScout's module installation feature extracts ZIP archives without validating file paths, allowing an authenticated admin to write files arbitrarily on the server filesystem via a specially crafted ZIP. Version 1.8.215 fixes the vulnerability.
