Description

Kimai is a web-based multi-user time-tracking application. Versions prior to 2.1.0 are vulnerable to a Server-Side Template Injection (SSTI) which can be escalated to Remote Code Execution (RCE). The vulnerability arises when a malicious user uploads a specially crafted Twig file, exploiting the software's PDF and HTML rendering functionalities. Version 2.1.0 enables security measures for custom Twig templates.
