A missing authorization flaw in Kimai allows an authenticated user to perform unauthorized actions by bypassing standard access controls.

This is a missing authorization vulnerability (CWE-862) occurring within the quick entry mechanism, which fails to properly validate the permissions of an authenticated user before executing certain operations.

The vulnerability is rated with a CVSS score of 8.8, reflecting the significant impact of unauthorized access. Successful exploitation could allow a standard user to manipulate data or gain privileges they are not entitled to, potentially leading to unauthorized data modification or administrative access.

Immediate Action: Upgrade Kimai to version 2.62.0 or later to ensure proper authorization checks are enforced.

Proactive Monitoring: Review application audit logs for suspicious activity involving the quick entry feature or unexpected privilege escalations by standard users.

Compensating Controls: Restrict access to the Kimai application to trusted network segments and ensure that user roles follow the principle of least privilege.

Public Exploit Available: Unknown

Administrators should apply the 2.62.0 update as soon as possible to remediate the authorization bypass. Ensuring that software is kept at the latest version is essential for maintaining the integrity of access control mechanisms within the application.
