CVE-2026-27316Network attack vector

Administrator LDAP credential disclosure via client-side inspection

Published Apr 14, 2026 · Updated Apr 14, 2026

Insufficiently protected credentials in Fortinet FortiSandbox and FortiSandbox PaaS allow remote authenticated users to read LDAP credentials. The LDAP configuration page returns saved LDAP server credentials to the browser, where client-side inspection exposes them. Administrator access to the GUI is required, and the consequence is limited to credential confidentiality in the affected releases.
