CVE-2026-80198Network attack vectorHinoki check available

Server-wide secret disclosure via unrestricted config lookup

Published Aug 25, 2026 · Updated Aug 25, 2026

Information disclosure in Kimai before 2.56.0 allows remote authenticated users to expose server-wide secrets through crafted Twig templates. StrictPolicy permits config(), whose fallback passes an attacker-selected key to SystemConfiguration::find() without restricting access to flattened configuration entries. Exploitation requires SUPER_ADMIN template-upload access, and LDAP or SAML secrets are exposed when another authorized user renders the invoice or export.
