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 App\\API\\Authentication\\ApiRequestMatcher routes an existing session through the main firewall. A Scheb TwoFactorToken satisfies that access rule, and App\\Voter\\ApiVoter 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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-52827)\n\nAffected packages:\n\n- `kimai/kimai < 2.59.0`\n\nPatched in:\n\n- `kimai/kimai 2.59.0`\n\nSource: https://github.com/advisories/GHSA-v8hx-4vx8-wc96","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":39.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":203576,"id":"CVE-2026-52827","ts":1789472201851,"field":"cvss","old":null,"new":"7.1"}]}
