## Overview

BerriAI litellm <=1.82.4 is vulnerable to Server-Side Template Injection (SSTI), which allows unauthenticated remote attackers to execute arbitrary OS commands via a crafted dotprompt_content parameter in the /prompts/test endpoint due to use of an unsandboxed jinja2.Environment.

## Affected packages

- `litellm < 1.83.7`

## Remediation

Upgrade to a patched release:

- `litellm 1.83.7`
