## Overview

calibreweb prior to version 0.6.17 is vulnerable to server-side request forgery (SSRF). This is a result of incomplete SSRF protection that can be bypassed via an HTTP redirect. An HTTP server set up to respond with a 302 redirect may redirect a request to `localhost`.

## Affected packages

- `calibreweb < 0.6.17`

## Remediation

Upgrade to a patched release:

- `calibreweb 0.6.17`
