## Overview

The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'not_found' parameter in all versions up to, and including, 3.3.58 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

## Remediation

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