HIGHPre-NVD 7.17.1—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 85% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
