Description

The Weaver Show Posts Plugin for WordPress is vulnerable to stored Cross-Site Scripting due to insufficient escaping of the profile display name in versions up to, and including, 1.6. This makes it possible for authenticated attackers with contributor-level and above permissions 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

  • wpweaver Weaver Show Posts — Up to and including 1.6
  • weavertheme weaver_show_posts — Up to and including 1.6
