CVE-2026-93954Public exploitNetwork attack vectorHinoki check available

Credential disclosure via unfiltered settings response

Published Sep 19, 2026 · Updated Sep 19, 2026

Incorrect authorization in Grimmory 3.3.0 through 3.4.1 allows remote authenticated users to read restricted application settings. AppSettingController.getAppSettings returns the complete settings object without applying the permission checks that protect administrative values. Any valid account can retrieve configured OIDC client secrets and third-party metadata API keys or cookies; disclosure depends on those values being configured.
