CVE-2026-11597
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceStored XSS vulnerability in the Surbma | Infusionsoft Shortcode WordPress plugin where the 'account' and 'id' shortcode attributes are directly concatenated into a <script> tag's src attribute without sanitization or escaping, allowing authenticated contributors+ to inject arbitrary JavaScript.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify the plugin is installedGo to WordPress admin > Plugins and check if 'Surbma | Infusionsoft Shortcode' is listed among installed pluginsAffected if The plugin is installed and active
-
Check the installed plugin versionIn Plugins list, click on the plugin to view details and note the version number; compare this to the version that includes the fix for CVE-2026-11597Affected if The installed version is older than the patched version containing the fix
-
Identify shortcode usage with vulnerable attributesSearch your WordPress posts, pages, and custom post types for the shortcode (typically [infusionsoft] or similar) containing 'account' and 'id' attributes; use wp-admin search or query the wp_posts table directlyAffected if Any published content contains the shortcode with 'account' and/or 'id' parameters
-
Inspect the plugin source code for missing sanitizationLocate the plugin PHP file handling the shortcode (usually in wp-content/plugins/surbma-infusionsoft-shortcode/) and examine how the 'account' and 'id' attributes are output into the script src attribute; verify whether esc_attr() or equivalent escaping is usedAffected if The code directly concatenates shortcode attributes into the script tag without escaping
You are affected if the plugin is active, the shortcode with 'account' or 'id' attributes is in use, and the plugin code lacks proper escaping for those attributes in the script tag.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataAdd proper input sanitization (e.g., esc_attr()) to the 'account' and 'id' attributes before outputting them in the script tag, and implement output escaping appropriate for HTML attributes.
