CVE-2026-53445: Wekan

High severity, CVSS 7.1. EPSS: 0.4% chance of exploitation in the next 30 days.

Wekan is open source kanban built with Meteor. Prior to 9.32, the Wekan copyBoard Meteor DDP method in server/publications/boards.js copies a board by caller-supplied board ID without checking this.userId, membership, or admin access. Any authenticated user can copy a private board they are not a member of, including its cards, checklists, custom fields, labels, and rules, while the REST POST /api/boards/:boardId/copy path correctly checks board admin access. This issue is fixed in version 9.32.
