Description

The ARMember Lite - Membership Plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 4.0.16 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

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

  • reputeinfosystems ARMember – Membership Plugin, Content Restriction, Member Levels, User Profile & User signup — Up to and including 4.0.16
  • armemberplugin armember — Up to and including 4.0.14
