## Overview

Kimai versions before 2.56.0 fail to restrict the config() Twig function in sandboxed invoice and export templates, allowing administrators to access arbitrary configuration keys. Attackers with admin privileges can upload malicious templates to exfiltrate server-wide secrets including LDAP bind passwords and SAML private keys into invoice or export documents accessible to lower-privileged users.
