CVE-2026-52827 – Kimai is an open-source time tracking application. Prior to 2.59.0, the KIMAI_SESSION cook

Kimai is an open-source time tracking application. Prior to 2.59.0, the KIMAI_SESSION cookie issued after password verification but before TOTP completion is accepted by every /api route because config/packages/security.yaml protects the API with IS_AUTHENTICATED and AppAPIAuthenticationApiRequestMatcher routes an existing session through the main firewall. A Scheb TwoFactorToken satisfies that access rule, and AppVoterApiVoter grants API access to its User, allowing an attacker with a valid account password to use authenticated REST API operations without entering the second factor even though web routes remain blocked. This issue is fixed in version 2.59.0.
