DescriptionVvveb 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 revision operations allow a low-privileged Author to access revisions for posts owned by another Author. The admin/controller/content/revisions.php controller and admin/sql/sqlite/post_content_revision.sql queries trust caller-controlled post_id, language_id, and created_at values without consistently applying the current admin_id to revision lists, reads, restores, and deletes. An attacker can read historic post content, restore a revision over another Author's live post content, or delete revision records, exposing drafts, corrupting published content, and removing audit history. This issue is fixed in version 1.0.8.4.
