CVE-2026-49226

High

Description

Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to 1.0.8.4, Vvveb backend post operations allow a low-privileged Author to access posts owned by another Author. The admin/controller/content/posts.php controller permits filter[admin_id] to replace the server-selected admin_id restriction and accepts a caller-controlled post_id for duplicate and delete actions, while admin/sql/sqlite/post.sql does not consistently enforce post.admin_id. An attacker can view post metadata, discover post identifiers, duplicate posts, or delete posts and related content, exposing private drafts and causing content pollution, data loss, or business disruption. This issue is fixed in version 1.0.8.4.
