CVE ID :CVE-2026-85743
Published : Nov. 6, 2026, 5:20 p.m. | 38 minutes ago
Description :FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.230, multiple outbound paths in Helper::downloadRemoteFile(), Helper::checkPort(), Helper::sanitizeRemoteUrl(), MailboxesController.php, and ModulesController.php do not consistently enforce a sink-level restricted-host policy. An authenticated administrator, or another authenticated user permitted to change mailbox connection settings or trigger module update or installation paths, can supply attacker-controlled URLs or hosts. The independent download and port-test sinks can reach encoded or otherwise uncovered loopback and internal addresses. The redirect-validation bypass additionally requires a configured whitelist that permits the original and final hosts while a restricted internal host appears only as an intermediate redirect hop. No unauthenticated SSRF path is established. The server can consequently contact loopback and internal services, provide a blind internal port oracle, and retrieve internal HTTP responses into application-controlled download sinks. This issue is fixed in version 1.8.230.
Severity: 8.2 | HIGH
