## Overview

mcp-from-openapi from 2.5.0 before 2.9.0 contains a credential exposure vulnerability that allows attackers to capture Authorization and Cookie headers because safeFetch() forwards them on cross-origin redirects. Attackers controlling a spec host or abusing an open redirect can redirect fromURL() spec requests to their own origin to steal bearer tokens or cookies.

## Affected

- `mcp-from-openapi >= 2.5.0 < 2.9.0`

## Remediation

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