CyberRota Analysis

AI-Generated

The Social Chat – Click To Chat App Button plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping in the 'consent_message' JSON attribute. This allows authenticated attackers with contributor-level access or higher to inject malicious scripts that execute automatically when users load affected pages. WordPress site administrators and developers using this plugin should prioritize patching to mitigate potential exploitation risks.

Original NVD Description

The Social Chat – Click To Chat App Button plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'consent_message' JSON Attribute in .qlwapp data-box in all versions up to, and including, 8.6.2 due to insufficient input sanitization and output escaping. 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. The exploit requires no user interaction beyond page load, as setting auto_open and consent_enabled to 'yes' in the injected data-box JSON causes the consent box — and the embedded script — to execute immediately on page load.
