Description

The Simple Download Monitor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via custom field in all versions up to, and including, 4.0.5 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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • mra13 Simple Download Monitor — Up to and including 4.0.5
