Wekan is open source kanban built with Meteor. Prior to 9.31, Wekan allows a logged-in board member to insert an attachment document through the \/attachments\/insert DDP method with attacker-controlled versions.original.path and versions.original.storage fields. The server\/permissions\/attachments.js insert rule checks only board write access, and FileStoreStrategyFilesystem.getReadStream() in models\/lib\/fileStoreStrategy.js streams the stored path without a storage-root containment check, allowing arbitrary file reads and denial of service through special files such as \/dev\/zero. This issue is fixed in version 9.31.<\/p>\n","protected":false},"excerpt":{"rendered":"
