CVE-2026-66416: Leantime CSRF protection disabled in global middleware stack

CVE-2026-66416 · Severity: high · CVSS 8.8 · Published 2026-07-30

Leantime is a project management system designed for small teams and individuals. A security flaw in the software allows attackers to trick logged-in users into performing unintended actions, such as deleting projects, changing account settings, or modifying permissions. This could lead to significant data loss or unauthorized access if a user visits a malicious website or clicks a link in a phishing email while logged into the application.

Technical details

A Cross-Site Request Forgery (CSRF) vulnerability exists in Leantime versions up to and including 3.6.2 due to the global omission of the Laravel 'VerifyCsrfToken' middleware in 'app/Http/Kernel.php'. Because this protection is disabled globally, every state-changing endpoint (POST, PUT, DELETE) is vulnerable. An unauthenticated remote attacker can exploit this by inducing an authenticated user to visit a specially crafted webpage or link. Successful exploitation allows the attacker to execute arbitrary actions with the victim's privileges, including project deletion, permission modification, and setting changes. A fix has been proposed in the project's repository to re-enable the middleware globally while exempting specific non-browser endpoints.
