CVE-2026-11597

Description

The Surbma | Infusionsoft Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'infusionsoft-form' shortcode in versions up to, and including, 2.0.1. This is due to insufficient input sanitization and output escaping on user-supplied 'account' and 'id' shortcode attributes in the surbma_infusionsoft_shortcode_shortcode() function, which are concatenated directly into a <script> tag's src attribute. 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.
