CVE-2024-32340Public exploitNetwork attack vector

Script execution via unescaped stored website title

Published Apr 17, 2024 · Updated Aug 14, 2024

Stored cross-site scripting in WonderCMS 3.4.3 allows attackers to execute arbitrary script through the Menu module's WEBSITE TITLE field. The application saves the siteTitle value without sufficient neutralization and renders it into theme title and metadata contexts, causing stored markup to execute in a visitor's browser. The poisoned value is created through the administrative settings interface, and execution requires a user to load a page that renders the stored title.
