CVE-2026-63104

Kaneo 2.3.12 < 2.12.2 Missing Authorization via Bulk Task Endpoint

Published Sep 22, 2026 CVSS 4.0 · 7.2 High EPSS < 1% KEV · Not listed
Description
Kaneo versions 2.3.12 before 2.12.2 contain a missing authorization vulnerability that allows authenticated workspace members with viewer or member roles to delete and modify tasks beyond their assigned permissions by exploiting the bulk task endpoint that omits workspace permission checks. Attackers can send requests to the PATCH /api/task/bulk endpoint, which verifies only workspace membership without calling the role-based permission check enforced on all other task endpoints, to permanently delete all tasks or modify task status, priority, assignee, due date, and labels in a workspace.
