EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 66% 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 9.35, the Wekan cloneBoard Meteor method in models/import.js uses caller-supplied sourceBoardId to build a board export through models/exporter.js without invoking canExport() or checking source-board membership. Any authenticated user who knows a private board ID can clone the board into their own account and read its cards, comments, attachments, member information, and activities. This issue is fixed in version 9.35.
