Description

The Mail Queue plugin for WordPress is vulnerable to Stored Cross-Site Scripting via an email subject in versions up to, and including, 1.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers 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

  • wdm-team Mail Queue — Up to and including 1.1
  • webdesignmunich mail_queue — Up to and including 1.1
