CVE-2026-40570

MEDIUM

FreeScout's Missing Authorization in load_customer_info Allows Any Authenticated User to Access Full Customer PII

Title source: cna
STIX 2.1

Description

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.213, the `load_customer_info` action in `POST /conversation/ajax` returns complete customer profile data to any authenticated user without verifying mailbox access. An attacker only needs a valid email address to retrieve all customer PII. Version 1.8.213 fixes the issue.
