The Ibtana - WordPress Website Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ive' shortcode in all versions up to, and including, 1.2.5.7 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
AnalysisAI
Stored cross-site scripting in Ibtana - WordPress Website Builder plugin up to version 1.2.5.7 allows authenticated contributors to inject arbitrary JavaScript via the 'ive' shortcode due to insufficient input sanitization and output escaping. When an injected page is accessed by any user, the malicious script executes in their browser with the privileges of their WordPress session, enabling session hijacking, credential theft, or administrative actions depending on victim privileges. No public exploit code or active exploitation has been confirmed at the time of analysis.
Technical ContextAI
The vulnerability exists in the Ibtana plugin's shortcode handler for the 'ive' shortcode, specifically in files such as ive-countdown.php where user-supplied shortcode attributes are processed without proper sanitization (via WordPress sanitize functions) or escaping (via WordPress escape functions like wp_kses_post or esc_attr). The root cause is CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page), a class of stored XSS vulnerability. WordPress shortcodes accept arbitrary attributes that, if not sanitized on input and escaped on output, can be used to break out of expected HTML contexts and inject script tags or event handlers. The affected CPE cpe:2.3:a:vowelweb:ibtana_-_wordpress_website_builder:*:*:*:*:*:*:*:* indicates this affects all versions of the plugin up to and including 1.2.5.7.
RemediationAI
Update the Ibtana - WordPress Website Builder plugin to version 1.2.5.8 or later, which includes fixes for input sanitization and output escaping in the 'ive' shortcode handler (per changeset 3485257 in the plugin repository). If an immediate update is unavailable, disable the 'ive' shortcode or restrict contributor-level access to trusted users only. Site administrators should audit existing pages for malicious 'ive' shortcode attributes, particularly those created by users with elevated privileges during the vulnerability window.
