EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.2 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. 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.
