Official description

Wekan is open source kanban built with Meteor. Prior to 9.32, Wekan webhook integration URLs in models/integrations.js are stored from user input and later fetched by server/notifications/outgoing.js without applying the existing validateAttachmentUrl() private-network checks from models/lib/attachmentUrlValidation.js. A board administrator can configure webhook URLs that cause server-side requests to internal or metadata services. This issue is fixed in version 9.32.
