Root Cause Analysis
The vulnerability stems from two key points: 1) Lack of input sanitization when saving menu link names (handled by the controller's postEdit
method), and 2) Lack of output encoding when rendering menu items (handled by the Blade
template). The reproduction steps explicitly involve editing menu links and observing XSS during rendering, implicating these components. While exact code isn't available, Lavalite
's Laravel
architecture and standard XSS patterns strongly support this analysis.
