## Overview

ValueCell through 0.1.20 contains an unauthenticated server-side request forgery vulnerability that allows remote attackers to direct backend requests by setting an unvalidated provider base_url. Attackers can set base_url via the provider config endpoint and trigger POST /api/v1/models/check to reach internal or metadata addresses, read error responses, and capture stored provider API keys.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
