CVE-2026-127215
Kanbanz WordPress Plugin < 1.0.3 Broken Access Control via admin-ajax Handlers
Kanbanz by Softaculous plugin for WordPress before 1.0.3 contains a broken access control vulnerability that allows authenticated Kanban Staff users to access and modify boards they are not members of by exploiting admin-ajax handlers that fail to call kanbanz_user_can_access_board() or per-task edit checks on attacker-supplied board_id or task_id parameters. Attackers can supply arbitrary board IDs to read sensitive task data, overwrite status columns, subtasks, and labels, inject comments, upload or delete attachments, and create tasks or set WIP limits on boards owned by other teams.
