EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 79% 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. From 9.57 until 9.74, the /api/boards/:boardId/exportExcel route in models/exportExcel.js called the asynchronous exporterExcel.canExport(user) authorization guard from models/server/ExporterExcel.js without awaiting it. The returned Promise was always truthy, so exporterExcel.build(res) ran even when board.isVisibleBy(user) would deny access, allowing any authenticated non-member to download private board card titles, descriptions, lists, swimlanes, members, and metadata. This issue is fixed in version 9.74.
