Lifecycle Timeline
4DescriptionGitHub Advisory
Kimai is a web-based multi-user time-tracking application. Prior to version 2.46.0, Kimai's export functionality uses a Twig sandbox with an overly permissive security policy (DefaultPolicy) that allows arbitrary method calls on objects available in the template context. An authenticated user with export permissions can deploy a malicious Twig template that extracts sensitive information including environment variables, all user password hashes, serialized session tokens, and CSRF tokens. Version 2.46.0 patches this issue.
AnalysisAI
Kimai versions prior to 2.46.0 contain an overly permissive Twig sandbox configuration in the export functionality that allows authenticated users with export permissions to execute arbitrary method calls and extract sensitive data such as environment variables, password hashes, and session tokens. Public exploit code exists for this vulnerability. The issue is resolved in version 2.46.0 and later.
