Two-factor authentication (TOTP) can be fully bypassed for the REST API. The KIMAI_SESSION cookie returned in the response to the login request; issued after only the password is verified, before the TOTP step; is already accepted as authenticated by every /api/* endpoint. So after submitting just the password, the web UI correctly holds the browser at the TOTP screen (/en/auth/2fa), but the cookie from that same login response can be …

Kimai 2.56.0 contains authenticated cross-site request forgery issues in its timesheet state-changing API endpoints. The application reuses the browser's existing session for /api/* requests, and both the stop and restart operations are exposed through GET and PATCH routes that directly modify business state. As a result, an attacker can trick a logged-in user into visiting a malicious page and cause unauthorized timesheet actions without the victim's consent. Depending on the …

Kimai 2.56.0 contains an authenticated improper authorization vulnerability in the preset-project activity creation flow. A user with the generic create_activity permission, but without access to a target project, can still create a new Activity under that unauthorized project by visiting the preset project creation route directly. This is a persistent cross-project business-object creation issue. The attacker does not need permission to view or edit the target project and only needs …

Kimai 2.56.0 contains an authenticated improper authorization vulnerability in the Web rate editing flows for projects, customers, and activities. A user who can edit one authorized parent object can combine that authorized parent ID with the rate ID of a different, unauthorized parent object and thereby modify the unauthorized rate record. This affects ProjectRate, CustomerRate, and ActivityRate editing. The issue is caused by missing parent-child consistency validation and allows cross-project, …

The ExportController web routes for creating and editing export templates are gated only by the class-level create_export permission, which is granted to ROLE_TEAMLEAD by default. The corresponding API routes and UI button visibility correctly require the stricter create_export_template permission, which is granted only to ROLE_ADMIN and ROLE_SUPER_ADMIN. A TEAMLEAD user can directly access the template create/edit routes to create or modify global export templates that are visible to all users …

The official Kimai Docker image ships with APP_SECRET=change_this_to_something_unique as the default environment variable. The Docker entrypoint does not override or validate this value. Any Kimai instance deployed using the Docker image without explicitly setting APP_SECRET runs with a publicly-known Symfony kernel.secret, enabling an unauthenticated attacker to forge HMAC-signed cookies and login links to take over any account including super_admin.

Kimai contains an authenticated improper authorization vulnerability in Team-related assignment APIs. A Teamlead who can edit their own team can use backend API endpoints to add users or activities that fall outside their intended visible or manageable scope, even when the frontend correctly hides those targets. This affects both team member assignment and team activity assignment. The issue is caused by treating "may edit this team" as equivalent to "may …

Kimai 2.56.0 contains an authenticated authorization bypass in the timesheet restart and duplicate workflows. After a user loses access to a project, the user can still derive a new timesheet from one of their historical entries and create a new record under that now-unauthorized project and activity combination. This is a permission revocation bypass with persistent write impact. The issue affects both restart and duplicate, which trust ownership of an …

Insufficient clearing of the output buffer in Java-based decompressor implementations in lz4-java 1.10.0 and earlier allows remote attackers to read previous buffer contents via crafted compressed input. In applications where the output buffer is reused without being cleared, this may lead to disclosure of sensitive data. JNI-based implementations are not affected.

After an API Token exposure from an exploited trivy dependency, two new releases of litellm were uploaded to PyPI containing automatically activated malware, harvesting sensitive credentials and files, and exfiltrating to a remote API. Anyone who has installed and run the project should assume any credentials available to litellm environment may have been exposed, and revoke/rotate thema ccordingly.
