CVE-2026-93954 Details
Description
A security vulnerability has been detected in grimmory-tools grimmory up to 3.3.3/3.4.1. Affected is the function AppSettingController.getAppSettings of the file backend/src/main/java/org/booklore/controller/AppSettingController.java of the component Settings API Endpoint. Such manipulation leads to incorrect authorization. The attack can be launched remotely. The exploit has been disclosed publicly and may be used. The name of the patch is 2b66ca6df8110f6b512e030b54c16b9fbe318f17. Applying a patch is advised to resolve this issue. PR #2558, merged as 53abc8b, moved the OIDC secret into a dedicated setting, but did not by itself restrict GET /api/v1/settings.
A vulnerability in the Grimmory digital library application, specifically in versions through 3.3.3 and 3.4.1, allows authenticated users to access sensitive OIDC client secrets and third-party API keys. This issue arises from the 'AppSettingController.getAppSettings' method, which lacks proper authorization checks. The vulnerability can be exploited remotely by any user with a valid account and JWT, without requiring administrative privileges.
Users are advised to update to Grimmory version 3.4.1 or later, where this vulnerability has been addressed by restricting access to the settings endpoint.
