Vulnerability Title
GreenShift - Animation and Page Builder Blocks <= 12.6 - Missing Authorization to Authenticated (Subscriber+) Information Disclosure of AI API Keys and Stored Cross-Site Scripting via custom_css
Source: NVD (National Vulnerability Database)
Vulnerability Description
The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the greenshift_app_pass_validation() function in all versions up to, and including, 12.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve global plugin settings including stored AI API keys and modify plugin settings, including the injection of arbitrary web scripts via the 'custom_css' value (stored XSS). NOTE: This vulnerability was partially patched in version 12.6.
