Description

The Instagram for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcodes in versions up to, and including, 2.1.6 due to insufficient input sanitization and output escaping on user supplied attributes. 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

  • esemono Instagram for WordPress — Up to and including 2.1.6
  • ink361 instagram_for_wordpress — Up to and including 2.1.6
