{"apiVersion":"1.0","identifier":"CVE-2026-68559","description":"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.","publishedAt":"2026-08-19T20:17:21","lastModifiedAt":"2026-08-19T20:17:21","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-68559","cvssScore":6.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","epssProbability":0.00294,"riskScore":0.67,"affectedProduct":"Wekan","affectedVersions":">=9.57,<9.74","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-68559","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-68559","en":"https://www.redsauce.net/en/cves/CVE-2026-68559","fr":"https://www.redsauce.net/fr/cves/CVE-2026-68559","pt":"https://www.redsauce.net/pt/cves/CVE-2026-68559","de":"https://www.redsauce.net/de/cves/CVE-2026-68559","sk":"https://www.redsauce.net/sk/cves/CVE-2026-68559","el":"https://www.redsauce.net/el/cves/CVE-2026-68559"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-68559"}}
