CVE-2026-45616 Details
Description
Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to 1.0.8.3, This vulnerability is fixed in 1.0.8.3.
A stored cross-site scripting vulnerability has been identified in Vvveb CMS versions prior to 1.0.8.3. The issue allows users with the Editor role to inject JavaScript payloads into post content, which are executed only when higher-privileged users (such as Administrators) edit the post. This vulnerability arises because the CMS does not properly sanitize HTML event-handler attributes before saving them, enabling passive session hijacking of administrators.
Users are advised to update to Vvveb CMS version 1.0.8.3 or later. Additionally, implement server-side HTML sanitization, using tools like HTMLPurifier with a strict allowlist, to remove event-handler attributes and javascript URIs from post content before saving.
